displaying a default image

[unistake]

Hi all,

 

I have this script below where I am trying to display a default image if an image can not be found.

 

For some reason though it is not working.

 

<?php 
foreach (glob('./aircraft/' . $rowX['reg'] . '[0-8].jpg') as $file)
{
   if (file_exists($file)) {
echo "<img src=\"" . $file . "\"  /><br />";
}
else { echo "><img src=\"aircraft/wrightflyer.jpg\" /><br />";}
}
?>

I'm not very familiar with "glob" but after looking at it, it only finds files that EXISTS so you will never run into a file that doesn't exist.

 

try this ?:

$files = glob('./aircraft/' . $rowX['reg'] . '[0-8].jpg') or array();
foreach($files as $file){
  if (!empty($file)) {  // GLOB already determined the file exists, check if array is empty
echo "<img src=\"" . $file . "\"  /><br />";

}

else { echo "><img src=\"aircraft/wrightflyer.jpg\" /><br />";}
}

I inserted that code, if the array has a file it displays it, but if there ISN'T a file it does not display the default image or show an error.

 

That code is a lot more logical than mine though

hmm.. ok .. maybe a for statement...

for($i = 0; $i <= 8; $i++){
  $filename = './aircraft/' . $rowX['reg'] . $i .'.jpg';
  if(file_exists($filename){
     echo "<img src=\"" . $filename . "\"  /><br />";
  } else {
    echo "><img src=\"aircraft/wrightflyer.jpg\" /><br />";
  }
}

 

This way you run thru all 0-8 occurences and can check each individual file without going thru the glob array.

That works Jocka but it is showing 8 default images - Should just be one!

 

There was also a bracket missing in your script line 3.

 

Any ideas?

$files = glob('./aircraft/' . $rowX['reg'] . '[0-8].jpg') or array();
if(!empty($file)) {
foreach($files as $file){
	?><img src="<?PHP echo $file; ?>"><br /><?PHP
}
}else{
?>
<img src="aircraft/wrightflyer.jpg"><br />";
}

Thanks got it working, you put $file instead of $files on line2.
