[RESOLVED] Condition: if an image file does not exist?

Joseph_Sliker

Hi;

I have a page that displays called-for images at a certain size. ie

$TCHR=$_POST[tchr];
echo "<img src=\"schedules/".$TCHR.".JPG\" width=800 alt=\"Schedule image.\" />";

This works fine if the image has been submitted and stored. But if NOT, it just displays a great big block with the missing image icon up in the corner.

Is there a simple way to test FIRST if the image: \".$TCHR.".JPG\" actually exists, and then, if not, display either nothing or a line of text saying that the image is not yet available?

Thanks?

Gah! This always happens...thinking about how to ask the question here seems to help me process what I need to search for in php.net. I think I need to figure out how to apply file_exists() to this problem.

<?php
$filename = '/path/to/foo.txt';

if (file_exists($filename)) {
    echo "The file $filename exists";
} else {
    echo "The file $filename does not exist";
}
?>

Yup. That's the ticket.

$filename = "schedules/".$TCHR.".JPG";
if (file_exists($filename)) {
   echo "<img src=\"schedules/".$TCHR.".JPG\" width=800 alt=\"Schedule image.\" />";
} else {
    echo "$tchrname's schedule has not been submitted.<br>";
}
echo "(Some sites have provided only site schedules.)<br>";
$sitefilename = "schedules/".$SCHOOLID.".JPG";
if (file_exists($sitefilename)) {
echo "<img src=\"schedules/".$SCHOOLID.".JPG\" width=800 alt=\"Schedule image.\" />";
} else {
    echo "A site schedule for $schl has not been submitted.<br>";
}
