I am in need of being able to upload files larger than 2MB, and am having trouble getting it to work. I am using php 4.3.11 and MySQL 4.1.8 on a Windows server under IIS.
I am aware of the three different ways of changing this value. I can do it in php.ini, but this is a shared server and it is not a good solution to change this globally. I can do it with .htaccess, but that's an apache only solution (AFAIK) and will not help me while running IIS. That leaves using ini_set() in a script, which is my preferred method anyway since it can be changed dynamically and in proper scope.
However, it's not working for me. Here's a function I created to present a form for choosing the file to upload:
function BlobEdit($aid,$blob=null)
{
ini_set('upload_max_filesize', '60M');
ini_set('max_execution_time', '999');
ini_set('memory_limit', '128M');
ini_set('post_max_size', '60M');
$trimcolor = GetConfigVar('TrimColor');
$uploadTypes = GetConfigVar('UploadType');
$page = "";
$page .= "<table width=\"95%\" border=\"1\" align=\"center\" cellpadding=\"1\" cellspacing=\"1\" style=\"border-collapse: collapse\">";
$page .= "<tr><td width=\"34%\" align=\"center\" bgcolor=".$trimcolor." nowrap><em><font color=\"#FFFFFF\" size=\"2\">File</font></em></td><td><form name=\"uploads\" action=\"index.php?func=detailedit&aid=$aid\" method=\"post\" enctype=\"multipart/form-data\"><input type=\"File\" name=\"blob\" size=\"60\"></td></tr>";
$page .= "<tr><td width=\"34%\" align=\"center\" bgcolor=".$trimcolor." nowrap><em><font color=\"#FFFFFF\" size=\"2\">Title</font></em></td><td><input type\"text\" name=\"blob_title\" id=\"blob_title\" size=\"70\"></td></tr>";
$page .= "<tr><td width=\"34%\" align=\"center\" bgcolor=".$trimcolor." nowrap><em><font color=\"#FFFFFF\" size=\"2\">File Type</font></em></td><td>".SelectList($uploadTypes,'uploadtype',null,"Select One",'ConfigVal','ConfigVal',null,null,'onChange="passText(this.form.uploadtype.options[this.form.uploadtype.selectedIndex].value);"')."<input type=\"text\" name=\"blob_req\" id=\"blob_req\" size=\"70\" ></td></tr>";
$page .= "<input name=\"abstractid\" type=\"hidden\" id=\"abstractid\" value=\"".$aid."\">";
$page .= "<tr><td width=\"34%\" align=\"center\" bgcolor=".$trimcolor." nowrap><em><font color=\"#FFFFFF\" size=\"2\">Description of File<br>(what does it show)</font></em></td><td align=\"center\" colspan=\"2\"><textarea name=\"blob_desc\" type=\"text\" rows=\"10\" cols=\"55\" id=\"blob_desc\"></textarea></td></tr>";
$page .= "</table>";
$page .= "<p align=\"center\">";
$page .= "<span class=\"instructions\">Click on the button below to Save the file.</span><br><br>";
$page .= "<input type=\"submit\" name=\"cmdSubmit\" value=\"Add and Save File\"><br><br>";
$page .= "</form>";
$page .= ini_get('upload_max_filesize')."<br>";
$page .= ini_get('max_execution_time')."<br>";
$page .= ini_get('memory_limit')."<br>";
$page .= ini_get('post_max_size')."<br>";
return $page;
}The ini_set() functions should set the values, and the ini_get() functions are there to confirm what's been set. I set the values high enough to be noticable. When the form is displayed, the values displayed are:
upload_max_filesize: 2M
max_execution_time: 999
memory_limit: (none shown)
post_max_size: 8M
Those values are default values from php.ini except for max_execution_time. When I try the script, no file is uploaded unless the file size is less than 2MB.
Looking closely at the php docs, it lists upload_max_size as PHP_INI_PERDIR, which I think means it can only be set in the ini and .htaccess files. Interestingly, it also notes that "PHP_INI_ALL in PHP <= 4.2.3". So we've lost an option since v4.2.3(?).
Anybody know more about this? Am I out of luck (other than php.ini) for setting this variable? Has anybody gotten this to work on Windows/IIS specifically, and if so can you show me an example?
Thanks
Rob
