to delete existing image
in template ADV_LINKS_ADD_EDIT
put this where you have the upload input right before
</div>
</fieldset>
<if condition="$show['editlink']"><div>
<input type="checkbox" name="deleteimage" value="1"> Check this box to delete current image.
</div>
</if>
in addlinks.php
in the routine: // ##### Do Edit Link
put
$deleteimage=$vbulletin->input->clean_gpc('p', 'deleteimage', TYPE_UINT);
below (it's at the beginning of routine)
$newlink = $vbulletin->input->clean_gpc('p', 'link', TYPE_ARRAY);
still in the same routine, locate
and add below it
else if(isset($deleteimage))
{
$imagedata = "";
$imagetype = "";
$imagesql = ", imagedata = '', imagetype = ''";
}
now, you can delete existing image
By doing this edit will the picture used previously automatically be deleted when another picture is uploaded?
Or will the user have to delete first and then upload a new picture?
Wouldn't it be better to have the "delete checkbox" appear only if there is an image present, while the "upload box" is not? Once deleted, or if there is no image, only the "upload" box would be present.
Another way of doing it would be to automatically check the "delete box" if the upload box is used. Causing the previous picture to automatically be removed.
Perhaps I am just not understanding? By default, do images get deleted if a new one is uploaded? (without this hack) In other words, is this hack only for those who wish to not have an image?
Please explain.
