Below is the script i wrote to upload my files to my webserver download director. it does work for smaller files but when a file of about 50mb is to be upload it does not work and shows blank page. the error messages i set to show in case of the script failure also does not show. i set the value of the post_max_size in php.ini file to 100M but to no avail.please help.

<form action="../cms/add.php" method="post" name="form3" id="form3" enctype="multipart/form-data">
  <table align="center">
    <tr valign="baseline">
      <td nowrap="nowrap" align="right">Description:</td>
      <td><input type="text" name="description" value="" size="32" /></td>
    </tr>
   
    <tr valign="baseline">
      <td nowrap="nowrap" align="right" valign="top">location:</td>
      <td><input type="file" name="filepath" size="32"/>
      </td>
    </tr>
    <tr valign="baseline">
     
      <td align="center" colspan="2"><input type="submit" value="ADD" /></td>
    </tr>
  </table>
</form>

Are you on a dedicated? Most likely you won't be able to do this on shared.

There are actually 3 things you have to adjust to get php to handle the larger files. post_max_size is one and the other two are memory related but I can't recall the names without looking it up.

You should also check max script execution time as well. Maybe it's very low and your script just times out?

First of all look into your php error log, it will most likely tell you the reason.

like everybody has said


you'll probably have the set the php limit in the ini or the file itself if it's timing out
