I wonder if you’re looking for the core attachment_url_to_postid() function that uses: $sql = $wpdb->prepare( “SELECT post_id FROM $wpdb->postmeta WHERE meta_key = ‘_wp_attached_file’ AND meta_value = %s”, $path ); $post_id = $wpdb->get_var( $sql ); Note the extra meta key _wp_attached_file check compared to your current snippet. If you need to check if an image url … Read more
sys_get_temp_dir is not a WordPress function, it’s a core PHP function. It cannot be modified or changed using WordPress constants. To modify this would require changes to the servers operating system by the root user. Instead, WP_TEMP_DIR can be used to influence the value of get_temp_dir which is a WordPress function. In the event that … Read more
You can simply create a text file and call it php.ini . Make sure the file has the text encoding “Unicode no BOM”, as that will work best for both linux and windows. Use an FTP client to make a new file on the server and that will generate a file with the correct permissions … Read more
If I am not mistaken, WordPress just creates these sizes. The only thing you can say is which image you want to pick of these sizes. You can use this piece of code to make the sizes appear inside of the dropdown. Make sure to place this inside the functions.php after adding the image_sizes. function … Read more
I just ran a test where I uploaded an image to media library, then renamed my root index.php file to break WordPress, but the image I uploaded was still available by accessing it directly with its wp-content/uploads/… URL. There are no .htaccess files in wp-content or uploads either, which means that, barring any plugins that … Read more
While the other answers cover part of the answer (old WP install), it is important to note: The options appear, if one of the options is set. They are stored via the keys upload_path and upload_url_path. Before: Run (or add directly in the DB) $ wp option set upload_path foo $ wp option set upload_url_path … Read more
The following provides you with a file upload: add_filter(“gform_column_input_content_21_9_3”, “change_column3_content”, 10, 6); function change_column3_content($input, $input_info, $field, $text, $value, $form_id) { $input_field_name=”input_” . $field[“id”] . ‘[]’; $tabindex = GFCommon::get_tabindex(); $new_input=”<input type=”file” name=”” . $input_field_name . ‘” ‘ . $tabindex . ‘ class=”YOUR-CSS-CLASSES” />’; return $new_input; } But what does ‘repeatable’ mean in this context? Do you … Read more
I did it in a different way. I just had to update the code from Gerasimos Tsiamalos Retina Plugin to WordPress 3.5., using image editor instead of image resize. This is how it looks like: function nothing_image_make_retina_size($file, $width, $height, $crop=false) { if ( $width || $height ) { $resized_file = wp_get_image_editor($file); if ( ! is_wp_error( … Read more
WordPress contains 2 media up-loaders. The Flash uploader allows the selection of multiple files while the browser uploader only allows 1 file at a time. To disable the Flash uploader add the following filter to functions.php add_filter(‘flash_uploader’, create_function(‘$flash’, ‘return false;’)); EDIT After further investigation it’s probably not a great idea to use create_function. A beter … Read more
You can hook the upload_mimes filter to accomplish this: add_filter(‘upload_mimes’, ‘wpse_43657_upload_mimes’); function wpse_43657_upload_mimes($mime_types){ $mime_types[‘rwp’] = ‘application/octet-stream’; return $mime_types; }
