buttons - onClick

[Anon]

Hello everyone!

I created a button, and I want this button to remove an image from a folder. I am trying to use onClick but it doesn't do anything when I click on it. Here's the code for my button:
print ("<input type=button onClick=\"event.php?section=removeFile(\"$logoFileDir/$eventIDArray[$index]$specialFileExtension\")\" value=\"Remove\">\n");

Does anyone see what's wrong?? the name of my file is "event.php" the name of the function in that file is "removeFile"

Thanks for your time!!

Well, first off i think your quotes are gonna give you a problem.... plus why not just sorround it with a form with an action pointing to event.php?

I tried that. I'm not exactly sure how it works to remove a file. It is going to my removeFile function but it's not passing the file name.

Can you see what is wrong?
$vRemoveFile="$logoFileDir/$eventIDArray[$index]$specialFileExtension";

I also have:
PRINT"<FORM NAME=\"remove\" ACTION=\"event.php?section=removeFile&orgID=$orgID\" METHOD=\"POST\">";

<INPUT TYPE="HIDDEN" VALUE="<?=$vRemoveFile?>" name="vRemoveFile">
<INPUT TYPE=Submit VALUE=Remove></form>

once I figure out why the $vRemoveFile isn't working how do I remove that file?? In removeFile function I have:

if(!unlink($vRemoveFile))
print("failed to delete $vRemoveFile, please contact administrator.<br>\n");

This give error message of:
Unlink failed (No such file or directory)

Any help would be greatly appreciated!

<INPUT TYPE="HIDDEN" VALUE="<?=$vRemoveFile?>" name="vRemoveFile">

change to

<INPUT TYPE="HIDDEN" VALUE="<?$vRemoveFile?>" name="vRemoveFile">

You had an extra equals

Actually try

<INPUT TYPE="HIDDEN" VALUE="<? echo $vRemoveFile; ?>" name="vRemoveFile">

use echo when you want to put the variables into the html (or printf or whatever you prefer).

that equals sign is a shortcut for echo I believe, try it out, I love it. 🙂

<?=$varname;?> is valid php code

that error message sound like the file isn't there. You might want to inlude the absolute directory in your removeFile() function

if(!unlink('/home/httpd/html'.$vRemoveFile))
or whatever your web server root is.

echo pwd;

to find out if you're not sure.
