    G'day All
    Just a quick question
    This is really a html more than a php question.

    Is it possible to have two buttons and have different actions for each
    button in the same form?

    Thanks

    yes but it's more of an HTML/JavaScript thing.

    use INPUT Type='BUTTON' to put a second button on your form. Then use the onClick method to assign an action to it. If you want it to submit your form then call document.formName.submit();

    Yep, it probably is...

    > Is it possible to have two buttons and have different > actions for each button in the same form?

    Yep, you can.

    <form etc> <input type="submit" name="first_submit_action" value="do this"> <input type="submit" name="2nd_submit_action" value="do that"> </form>

    When you process your form in php you'll find that you have either $first_submit_action or $2nd_submit_action set to a value (well, if you have register global on anyway).

    So, you look for which one is set and act accordingly.

    Works for me...

    CYA, Dave

    No, because the action belongs to the form, not the submit buttons (which is why action is an attribute of form).

    However, you can use different names and values for the submit buttons, so that you can tell which was pressed on your receiving page. This way you can act accordingly, which is probably what you wanted to know.

    Hope that helps.

    Exactly.

    For starters, use this bit of HTML/PHP code to help you see what the browser sends you when the form is submitted (add this to the receiving page):

    <pre> <? print_r($_REQUEST); ?> </pre>

    Alternatively, you can choose to output $_GET or $_POST (instead of $_REQUEST) depending on which method you choose for your form. This will show you how to identify which button was pressed.

    Good luck.

    Ok :) These 2 functions will do what you want I think...

    function array_ref_push(&$array,&$ref){ $array[] =& $ref; } function &array_ref_pop(&$array){ $r =& $array[count($array)-1]; array_pop($array); //throw away a real pop return $r; }

    //Testing $stack = array(); $var = 1; array_ref_push($stack,$var); echo '<pre>'; print_r($stack); echo '</pre>'; $var = 2; echo '<pre>'; print_r($stack); echo '</pre>'; $var2 =& array_ref_pop($stack); echo 'var2 = '.$var2.'<br>'; $var = 3; echo 'var2 = '.$var2.'<br>'; echo '<pre>'; print_r($stack); echo '</pre>';

    I have the following problem:

    I have a DB named 'fotografias' with the following information:

    ind, indice_bio and url are fields names.

    I wrote the following code:

    <?php

    printf("<tr><td>&nbsp;%s&nbsp;</td></tr>", $row1["url"]); echo("<br>"); } mysql_free_result($respuesta); mysql_close($dbase); ?>

    I think I see where you're going, but I'm not sure that's the correct avenue here. If slashes from magic_quotes were in the string before encryption, wouldn't they be in the string after decryption? Why would that result in data corruption?

    Are you sure? I read the manual the other way...that the *result* is a multiple of blocksize:

    "This function encrypts data. The data is padded with "\0" to make sure the length of the data is n * blocksize. This function returns the encrypted data. Note that the length of the returned string can in fact be longer then the input, due to the padding of the data."

    I am storing the encrypted, padded string.

    This would imply that any non-blocksize-length strings would be corrupted which is not the case. 99% are fine.

    > require that you store the IV for each encryption along with the > ciphertext, but that's fine, as storing the IV along with the ciphertext is > not a security problem.

    However changing now will mean handling some historical data differently somehow. :( And storing an IV for each record would of course increase the data size.

    you're not differentiating between form elements on different rows. all the hidden elements have the same name and are in the same form so only the last one will be available as all the submit buttons are in the same form.

    you need to put <form ...>...</form> tags around each submit/hidden pair.

    attached mail follows:

    print "<form ...>"; print"<INPUT TYPE='submit' value='View details' Name='Details'>"; print"<input type='hidden' name='SelectedItemNumber' value='{$row[Id]}'"; print "</form>";

    you'll then have as many forms as you have rows and which one is submitted will depend on which button is pressed.

    Hi,

    I was playing around with error handlers, and tried this:

    <?php

    error_reporting(E_ALL ^ E_NOTICE);

    function ErrorHandler($_ErrorNumber_, $_ErrorString_, $_ErrorFile_, $_ErrorLine_, $_ErrorContext_) { mail("briangzmarketing.com", "Error", "Blah blah blah"); }

    set_error_handler("ErrorHandler");

    ...

    ?>

    Which worked just fine. A little too good, in fact.

    I got over 1,200 emails in a matter of minutes (high traffic site).

    I was finally able to get it to stop by re-declaring the function without the mail() call, but how do I restore PHP's default error handler?

    I haven't had any success with restore_error_handler();

    Thanks, Brian

    I'm not sure whey restore_error_handler() isn't working, but I have something else which may help you. When you use a custom error handler your function will handle ALL errors, regardless of your current error_reporting level. To make your function honor the current error_reporting level, put this line at the top of your function:

    if (!($_ErrorNumber_ & error_reporting())) return;

    This will also allow your function to ignore errors on function calls that you have prefixed with an '', since the '' temporarily sets the error_reporting level to 0.

    "\\1<a href=\"mailto:\\2\">\\2</a>", $text);

    I did not check the entire regexp but it seems to do what you need. Um, the NOT thingy in a regexp is the ^ in stead of the !.

    And my line will not tagify any email preceded by a forward slash.

    I'm using Flash very often within websites. Like you know, sometimes the user doesn't have the Flash-plug-in so I was wandering if I could depend on this $_SERVER['HTTP_ACCEPT'] variable to look for "shockwave-flash". If found, the visitor has Flash-plugging, if not, he doesn't.

    So my question really is, can I base my Flash-detection on this global variable or is too uncertain? (e.g. when the user is using Netscape, Opera etc., Linux, Mac etc.)

    Hi,

    I have currently working a Red Hat 7.2 system that installs PHP 4.0.6 from the CD and it works fine. I want to upgrade to ver 4.3.0 what would be the simplest way to do this without breaking any of the old modules etc. I wont mind making changes to my scripts in case of changes between versions.

    Do i need to remove the old PHP installation before building the new one ?

    Would using the configure command that shows in the <? phpinfo() ?> currently (with 4.0.6) work with the ver 4.3.0 ?

    Thank you

    If your old PHP was automatically installed by RH then just do an "rpm -e php" (maybe rpm-r php-4.0.6. To find out the write string to use to rpm -qa | grep php)

    > Do i need to remove the old PHP installation before building the new one > ?

    No, if you don't you need to take extra steps. And I can't see why you want to keep the old version around anyway.

    > Would using the configure command that shows in the <? phpinfo() ?> > currently (with 4.0.6) work with the ver 4.3.0 ?

    Most probably. SO I suggest downloading the 4.3.0 source files and doing a ./configure with the options you can from phpinfo() and then compiling :)

    Hi.

    Would it be possible to use PHP to communicate with a serail device e.g. a modem. I would like to send AT commands to a GSM modem & be able to read the resulting output.

    I know PHP may not be ideal for this, but I think if it's possible, it would be the quickest way of knocking something together.

    Assuming line 22 is (it would help if you told us _which_ is line 22)

    $smarty->assign("message", $message);

    and assuming that you _really_ have defined $smarty in the main code then I cannot see what you're doing wrong.

    Does $smarty->assign("message", $message work in the main loop (ie when not in a function)?

    Are you sure $smarty = new Smarty is in the main code? Can it be in another function?

    Try setting global $smarty; just before you create $smarty.

    Does that help?

    I'm creating an e-commerce website, and I just need clarification as to whether a MySQL query is considered as "browser output". I ask because I have the following code, but the cookie isn't being set:

    if ($op == "login") { if (!isset($username) && !isset($userpass)) { } else { if ($username == "" || $userpass == "") { $errormsg = "Invalid username or password. Please try again."; } else { if (mysql_num_rows(mysql_query("select * from `$cart->user_table` where username=\"$username\" and userpass=\"$userpass\"", $cart->dblink)) == 1) { setcookie("jackloren_user", "$username:$userpass", time() + 2592000); // expires in 30 days header("Location: http://www.jackloren.com/"); // echo "test"; /* if ($rd != "") { redirectURL($rd,""); } else { redirectURL("",""); } */ } else { $errormsg = "Invalid username or password. Please try again."; } } } }

    However, if I comment out the header and uncomment the echo statement, then the cookie is added, no problem. It seems as if the browser is freaking out when there isn't any output after a cookie is set and a header is sent.

    I'm also having another similar problem with this function:

    function auth($redirect_url) { global $HTTP_COOKIE_VARS; if (!isset($HTTP_COOKIE_VARS['jackloren_user'])) { header("Location: http://www.jackloren.com/login.php"); // echo "test"; } else { $userinfo = explode(":", $HTTP_COOKIE_VARS['jackloren_user']); $username = $userinfo[0]; $userpass = $userinfo[1]; echo "$username | $userpass<br>"; if (mysql_num_rows(mysql_query("select * from `$cart->user_table` where username=\"$username\" and userpass=\"$userpass\"", $cart->dblink)) != 1) { redirectURL("login.php", $redirect_url); } else { echo "success"; // nothing } } }

    If I leave the script the way it is, the browser isn't redirected no matter what I put in the header() statement. However, if I uncomment the echo statement, giving the browser some output, then the redirect works fine.

    Has anyone experienced this? And if so, how do I fix it? Thanks.

    Hi all !

    I am currently writing some kind of Document/File-Library in a LAMP environment.

    As the library should be able to handle various file types, and most file types have to be handled differently internally, I would like to use Objects/Classes to make the code for the Library iself independent from the stuff that is individual to the different file types.

    Now I noticed early that when I use Objects in PHP and have to create many for them each time a script runs it slows the system down considerably. It seems you can now save objects in sessions which AFAIR was not possible last time I tried. But then I would have to read the whole file index (which is actually a tree) into a session variable for each user, and I don't know if thats a good idea performancewise. It would be a rather large multi-dimensional array.

    So I would like to know if there is any possibility in PHP to create my own persistent superglobal, a variable which can be read by any script running. I think something similiar is available as the "Application" Object in ASP under IIS. I know I have to take care of locking and stuff (although the end-user scripts would only need read access to it), but if I could write some functions which just would check if the tree is already in memory or not (after a server shutdown or whatever), and if not just read it in from the database to make it available in every other script.

    The only thing I've found so far which I think may be a possibility is the shared memory stuff that PHP supports, but I don't know anything about that on the system level, and its not explained in much detail in the PHP manual. Is that something I should follow, or can't I use it ? Can I somehow use the underlying Apache ? Are there better options ?

    any help/suggestions/hints are greatly appreciated !

    A pretty easy way of doing it is to add a size field to the table. Whenever you INSERT INTO or UPDATE the table, update this field to contain the size of the data for the current record. Then, whenever you need to check the amount of data for a particular user, just use this query:

    "SELECT SUM(size) FROM sometable WHERE user=someuser"

    Hope this helps

    PS. Ive done this in a file upload script I created a while ago. If you want, I can mail you the relevant bits and bytes. DS.
