Safe Mode

Vienna

Hi there.
I am skilled asp programmer and database admin. so a friend of mine asked me for help, but PHP is not the language i worked with a lot.

he sent me a code fragment, which wont work, since his provider turned on "safe mode" on the server, and he also told him that the "IF" statement has to be changed therefore.
My question now, how should the "IF" statement should look like, to work within safe mode.

here the not working one:

#################################################
if (file_exists ($bild))
{
if ($format == "T-Shirt" or $format == "Crewneck" or $format == "Hooded Sweat")
{
echo "<a href='javascript:details(\"$interpret\", \"$titel2\", \"$format\", \"$artikelnr\", \"$seid\")'>";
echo "<img src='covers/siehedetails.gif' width='69' height='69' border=0>";
echo "</a>";
}
else
{
echo "<a href='javascript:details(\"$interpret\", \"$titel2\", \"$format\", \"$artikelnr\", \"$seid\")'>";
echo "<img src='".$bild."' width='69' height='69' border=0>";
echo "</a>";
####################################################

thank for help in advance.

regards

IF statement works fine in safe_mode.
It's the file_exists() functions that you'll be wrestling with.

Check the warning on file_exists() page.

thanks for this hint....
but i am still not sure how this if statement should look like....
which function should i use instead of file_exists() ??

Don't you guys have if statements in ASP (didn't bother searching)? It's the old "start 'if' bracket, close 'if' bracket" or "even number of brackets" stuff.

It should look like this:

<?php

if (file_exists($bild)) {

if (($format == "T-Shirt") || ($format == "Crewneck") || ($format == "Hooded Sweat")) {

    echo "<a href='javascript:details(\"$interpret\", \"$titel2\", \"$format\", \"$artikelnr\", \"$seid\")'>";
    echo "<img src='covers/siehedetails.gif' width='69' height='69' border=0>";
    echo "</a>";

} else {

    echo "<a href='javascript:details(\"$interpret\", \"$titel2\", \"$format\", \"$artikelnr\", \"$seid\")'>";
    echo "<img src='$bild' width='69' height='69' border=0>";
    echo "</a>";

}
}

I'm afraid for your last question I'm not that versed.

its not about the if statement generally....
i know about the brackets and the rest, looks similar to C#
but what i ask for is....obviously the function file_exists does not work within safe mode.
therefore i expect something different....maybe another function to use?
i searched the net, but maybe i searched wrong, because i couldnt find anything else to use instead.

fact is the code works perfect in safe_mode OFF....but not i safe_mode ON

so all i want to know is, what i should use instead of this function to check if the picture (file) exists?

I don't see why having safe_mode turned on should impact file_exists() in any way, other than perhaps if the file pathname being passed to it is in a directory not accessible by the script due to safe_mode restrictions. If that is the case, changing the PHP syntax/function won't help any.

It might help to know what the exact error message is you are seeing (or is in the PHP error log), along with an indicator as to which line of code it is citing.

Vienna

the line of error IS the if statement.
as far as the host-provider said.
He changed the settings of the php server (safe_mode ON) without any notice to my friend.
as he then asked the provider, he said, the if staement has to be changed, and if he is not able to do, the provider offered help...but with 120 euros an hour of course :evilgrin:

so, since he is my friend, i offerd him to investigate for a solution...for a free beer :-)

NogDog

Try adding this to the top of the script, and see if you get any more error information:

<?php
ini_set('display_errors', 1); // change to 0 for production version when done debugging
error_reporting(E_ALL);
/* rest of script . . . */

The best (and only, IMHO) solution is to tell your friend to stop wasting money on an incompetent provider and find one with at least 76% of a brain. There's aboslutely no reason to waste money on such a terrible provider when there are countless others out there competing for your business (and your satisfaction - imagine that!).

Otherwise, you'll have to do as NogDog suggests and get some more information. [man]file_exists/man works just fine in safe mode, provided that you stay within the restrictions that safe mode imposes.
