Hi,

when making an input field for submission from a form, I need to put a
name='something' in it. For CSS I often use an id='something'. Some
browsers apparently submit the field properly if name is missing and id is
present. Others might not. Can anyone tell me about what browsers do what?

Thanks,
Niels

HTML Forms should always use the NAME attribute to pass values, never ID.
You can use print_r($_REQUEST); at the top of your script to debug.

Thank you for your answer. W3C says:

[http://www.w3.org/TR/html4/interact/forms.html]

name = cdata [CI]
This attribute names the element so that it may be referred to from style
sheets or scripts. Note. This attribute has been included for backwards
compatibility. Applications should use the id attribute to identify
elements.

So my question remains: How well do browsers support using only id?

Uh, sorry to disappoint, but that's a description of the form element,
not of the input element or select input.

In fact, if you go to
http://www.w3.org/TR/1999/REC-html401-19991224/interact/forms.html#h-17.4.2
, you will see that the example form quite clearly uses name. And for
the input element,
http://www.w3.org/TR/1999/REC-html401-19991224/interact/forms.html#h-17.4.2
says that name assigns the control name.

The attributes for the form element are completely independent of the
input elements. (Note, for things like radio buttons, using id makes no
sense. You must have multiple elements with the same name. If you used
id for these multiple elements, you would be breaking the rules of html
saying only one element can have a certain id . . .)

Thanks for the help.

Yeah problem was with php.ini file.

Entry for memory limit is 12MB in the file actually it should read 12M (not 12MB).

Hi,
Thanks, putting the addtype in the <directory> section seems to have solved
the problem.

Yes, you are correct that in the statement:

$image = imagecreatefromjpeg($fileContent);

The variable $fileContent should be a file name -- but it's the
contents of the file that the function uses. So, what's the
difference between a filename and its contents? Is there a header I
should add? Or does the routine require a read operation?

I'll look at some other functions.

Thanks for your help.

Dynamic Thumbnail generation:
<http://www.weberdev.com/ViewArticle-388.html>http://www.weberdev.com/ViewArticle-388.html

Yes, that's for generating a thumbnail from a file -- but I want to
do it directly from a stored image from mySQL.

Any ideas?

Thanks for your help.

Hi:

The following works for me. It takes an image from mySQL (which is
stored as a string, duh!) and creates a thumbnail "on the fly".

Many thanks for your ideas -- you made me think.

tedd

<code>

$dbQuery = "SELECT image_type, image, image_width, image_height ";
$dbQuery .= "FROM pictures ";
$dbQuery .= "WHERE image_Id = $pic_id";
$result = mysql_query($dbQuery) or die("Couldn't get file list");

if(mysql_num_rows($result) == 1)
{
$fileType = mysql_result($result, 0, "image_type");
$fileContent = mysql_result($result, 0, "image");
$width_orig = mysql_result($result, 0, "image_width");
$height_orig = mysql_result($result, 0, "image_height");

// Set a maximum height and width
$width = 200;
$height = 200;

if ($width && ($width_orig < $height_orig))
    {
    $width = ($height / $height_orig) * $width_orig;
    }
else
    {
    $height = ($width / $width_orig) * $height_orig;
    }

// Resample
$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefromstring($fileContent);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height,
$width_orig, $height_orig);

// Output
imagejpeg($image_p, null, 100);
}

That's nice.

Now go check out the basic tutorials on the main PHP page. Click "Getting
help", then the "links" under the heading "Sample Code". When the PHP Links
page loads, scroll down to Tutorials.

http://ca3.php.net/links.php

Work through a couple, then check out how PHP does sessions so you do not
have to pass stuff through the URL.

Cheers - Miles

The cleanest solution is to use relative paths so that your site will work
regardless of where it's placed on the web server. Sometimes it can be
tricky to determine what the relative path should be, but PHP can help solve
that. Simply write a function or method to calculate the path to the base
directory of the site. Make this a global variable and echo it before any
path to a resource on the site.

global $PATH;

echo "<a href=\"{$PATH}images/blah.gif\" />\n";
