I have created a WordPress plugin where you can choose a file with the media uploader:
<input type="text" id="clb_setting_logo" name="clb_plugin_options[clb_setting_logo]" value="<?php echo esc_url( $options['clb_setting_logo'] ); ?>" />
<input id="upload_logo_button" type="button" class="button" value="<?php _e( 'Choose Image', 'clb' ); ?>" />
<span class="description"><?php _e('Choose an image for the button.', 'clb' ); ?></span>
When I choose an image from the media uploader the path is taken into the field #clb_setting_logo which can be seen above.
Within another function I try to access the dimensions as this:
if (!empty($options['clb_setting_logo'])) {
$imagesize = getimagesize($options['clb_setting_logo']);
It runs perfectly on two servers, on another server getimagesize returns bool(false), but why? First I thought this happens because the normal file path is taken - so something like this: "http://exmaple.com/wp-content/uploads/2016/02/test.png" - but this works on other installations.
Does anybody know something? Thanks!
