[PHP] trying to combine two forms into a single form
I have a mediawiki extension that allows me to design a form in the wiki to
facilitate data entry into the wiki and it works good except that I also
want to be able to up load images and take the file location/name and enter
that into the wiki so that the image displays on the page as well. I found
code online that works well for uploading an image to a site and it works
good in my mediawiki but when I combined the forms on a single page and
click on the upload button it wipes the other textarea fields clean
and doesn't submit the text data but it does upload the image and return the
path and filename. I know this is supposed to happen but I don't totally
understand why. If I just click on the save form button the image isn't
upload, but the text data is saved, again I understand something having to
do with two different forms/form handlers but I have been trying to combine
them with no luck. My line of thinking was to write a function to submit
the second form and call it when the first form is submitted but
this doesn't seem to be working or I am doing it wrong. The ultimate goal
is to have a form that submits issues into a knowledge base and allows
screenshots of error messages.
Here is the code for the page.
?php
//define a maxim size for the uploaded images in Kb
define (MAX_SIZE,1024);
//This function reads the extension of the file. It is used to determine if
the file is an image by checking the extension.
function getExtension($str) {
$i = strrpos($str,.);
if (!$i) { return ; }
$l = strlen($str) - $i;
$ext = substr($str,$i+1,$l);
return $ext;
}
//This variable is used as a flag. The value is initialized with 0 (meaning
no error found)
//and it will be changed to 1 if an errro occures.
//If the error occures the file will not be uploaded.
$errors=0;
//checks if the form has been submitted
// if(isset($_POST['Submit']))
//{
//reads the name of the file the user submitted for uploading
$image=$_FILES['image']['name'];
//if it is not empty
if ($image)
{
//get the original name of the file from the clients machine
$filename = stripslashes($_FILES['image']['name']);
//get the extension of the file in a lower case format
$extension = getExtension($filename);
$extension = strtolower($extension);
//if it is not a known extension, we will suppose it is an error and will
not upload the file,
//otherwise we will do more tests
if (($extension != jpg) ($extension != jpeg) ($extension !=
png) ($extension != gif))
{
//print error message
echo 'h1Unknown extension!/h1';
$errors=1;
}
else
{
//get the size of the image in bytes
//$_FILES['image']['tmp_name'] is the temporary filename of the file
//in which the uploaded file was stored on the server
$size=filesize($_FILES['image']['tmp_name']);
//compare the size with the maxim size we defined and print error if bigger
if ($size MAX_SIZE*1024)
{
echo 'h1You have exceeded the size limit!/h1';
$errors=1;
}
//we will give an unique name, for example the time in unix time format
$image_name=time().'.'.$extension;
//the new name will be containing the full path where will be stored (images
folder)
$newname=images/.$image_name;
//we verify if the image has been uploaded, and print error instead
$copied = copy($_FILES['image']['tmp_name'], $newname);
if (!$copied)
{
echo 'h1Copy unsuccessfull!/h1';
$errors=1;
}}}
//If no errors registred, print the success message
if(isset($_POST['Submit']) !$errors)
{
echo h1File Uploaded Successfully! Try again!/h1;
echo $newname=images/.$image_name;
}
function wfSpecialAddactivity() {
global $wgOut, $wgScriptPath;
$mine = $wgScriptPath.'/index.php?action=submit';

Re: [PHP] trying to combine two forms into a single form
The two forms work fine by themselves, my issue is getting to two of them to work with together, I don't even care if you need to upload the image seperately from submitting the text data as long as it is all on the same page. Thanks for the thoughts on jQuerry, I will look into it.

Re: [PHP] trying to combine two forms into a single form
I believe this is it. It is part of the mediawiki extension that I used as
a starting point for what I need it to do. I am slowly getting better at
PHP, this was dropped into my lap and I don't have much experience yet with
PHP, I come from bash/sed/awk land. This file is structuredinput.php, there
is only one more php file in the extension call specialstructuredinput.php
and I included that after this one as well.
Thanks

Re: [PHP] trying to combine two forms into a single form
Actually if you want a very simple way, with a little JS, you can b64 encode the file and fill in the file field in the form with it (you can hide it or dynamically tack it on or something), so that you get everything when you submit the form including the file (you just gotta make a file back out of it, but thats simple :) )...? I think that would be by far the easiest solution, then you can do the shiny ajax stuff later if you feel like it. -- The trouble with programmers is that you can never tell what a programmer is doing until it’s too late. ~Seymour Cray On Thu, Jun 9, 2011 at 11:10 AM, Jim Lucas li...@cmsws.com wrote: On 6/9/2011 8:07 AM, matty jones wrote: The two forms work fine by themselves, my issue is getting to two of them to work with together, I don't even care if you need to upload the image seperately from submitting the text data as long as it is all on the same page.
