Default Image is being deleted.

Default Image is being deleted.

I've tried several things to stop this from happening. I have the "Delete File" behavior on both my "Delete" page and my "Update" page. This works very well, but I just realized that if the default image is assigned to a record during Insert, and then later updated or deleted, not only are the images deleted as desired, but so is my default image. Not sure why I was thinking it wouldn't do that.

My attempts to correct this have been to put the default image in a sub folder since the Delete File behavior asks for the deletable folder. It still deletes the file.
I also tried adding the full path to that field thinking maybe it would write a new version to the upload folder each time it uses the default image, but it just simply inserted the path into the column of the table, which then didn't work because my php code includes a path before the binding of the image placeholder.

I'm sure that this is a simple fix, and I am just over thinking it. Any help would be appreciated.

Thanks,
TroyD

Please send a copy of your page so I can look at the code.

Jason,

Which page should I start with, the Insert that uploads and includes the default image file, or the Delete and/or Update page that is deleting it?

Ok, here it is. I got confuse because you were helping with an issue in another thread. I had two versions of the same file. Anyway, here is the version with the delete file behavior.

Ok, we can get around the issue by editing the delete file code.


Is the default file name the same for all three image fields?

the edit will look like this:

php:
<?php

$WA_DeleteFileResult1 
false;
if(isset(
$_POST["Update_x"])){
$WA_DeleteFileResult1 WA_FileAssist_DeleteFile("../images/hedgehogs/""".($row_rsAvailableHH['imagethumb1'] != "defaultFileName.ext")?$row_rsAvailableHH['imagethumb1']:""  ."");
}
?>




what we're changing is the file name portion of the delete file code, originally, it looked like:

php:
$row_rsAvailableHH['imagethumb1']



we changed it to:

php:
($row_rsAvailableHH['imagethumb1'] != "defaultFileName.ext")?$row_rsAvailableHH['imagethumb1']:""




this is a ternary expression that basically say's:
Does $row_rsAvailableHH['imagethumb1'] Not Equal "defaultFileName.ext"?
Yes - Use $row_rsAvailableHH['imagethumb1'] for the file name
No - use "" for the file name


you will need to substitute defaultFileName.ext for the actual default file name. if it is a different default file name for each file upload, you will need to change each of the delete file instances to reflect the proper file name.

Jason,

Thanks and yes, the default image is the same for all three. I'm heading in now to give this a try. I really appreciate the help.

Followup

Jason,

Do I need to change the triggering of the delete file for the 2nd and 3rd behavior? I ask because the fix worked great for the form that only had one image. I inserted a dummy record, then deleted it and the default image stays on the server.

But when I do this with the form containing the 3 images, all using the same default image, it gets deleted. I'm not sure if I am missing something in my code update. Here is the server behavior for all 4 deletes. The first three are for the first recordset (with 3 images) the 4th is is for the second recordset (with one image) and is working.

php:
<?php

$WA_DeleteFileResult1 
false;
if(isset(
$_POST["Delete_x"])){
    
$WA_DeleteFileResult1 WA_FileAssist_DeleteFile("../images/hedgehogs/""".($row_rsAvailableHH['imagethumb1'] != "PhotoUnavailable.jpg")?$row_rsAvailableHH['imagethumb1']:""  ."");
}
?>
<?php
$WA_DeleteFileResult2 
false;
if(isset(
$_POST["Delete_x"])){
    
$WA_DeleteFileResult2 WA_FileAssist_DeleteFile("../images/hedgehogs/""".($row_rsAvailableHH['imagethumb2'] != "PhotoUnavailable.jpg")?$row_rsAvailableHH['imagethumb2']:""  ."");
}
?>
<?php
$WA_DeleteFileResult3 
false;
if(isset(
$_POST["Delete_x"])){
    
$WA_DeleteFileResult3 WA_FileAssist_DeleteFile("../images/hedgehogs/""".($row_rsAvailableHH['imagethumb3'] != "PhotoUnavailable.jpg")?$row_rsAvailableHH['imagethumb3']:""  ."");
}
?>
<?php
$WA_DeleteFileResult4 
false;
if(isset(
$_POST["Delete2_x"])){
    
$WA_DeleteFileResult4 WA_FileAssist_DeleteFile("../images/hedgehogs/""".($row_rsStickyHH['imagethumb1'] != "PhotoUnavailable.jpg")?$row_rsStickyHH['imagethumb1']:""  ."");
}
?>



I can try creating a duplicate copy of the default image and just rename the second two if that would be better. But I wondered if I am missing anything here that would can see.
Thanks,
TroyD

Eric,

Just an FYI. I tried changing the trigger for the 2nd and 3rd delete behaviors thinking that might help. It didn't as I'm sure you already would know. I tried changing the 2nd to trigger after the 1st successfully deleted and the 3rd to trigger after the 2nd had successfully deleted. Not sure what else to try accept maybe creating 3 of the same default and giving them different names for each. I'll report back.

Thanks,
TroyD
