for timthumb in my wordpress i use this code to function first_image() { global $post, $posts; $first_img = ''; ob_start(); ob_end_clean(); $output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $post->post_content, $matches); $first_img = $matches [1] [0]; if(empty($first_img)){ //Defines a default image $first_img = "images/default.gif"; } return $first_img; } it works really well, then i thought why not to make it show random images if timthumb dont find any image? so the 1st googling i did came up with this function: <?php function getRandomFromArray($ar) { mt_srand( (double)microtime() * 1000000 ); $num = array_rand($ar); return $ar[$num]; } function getImagesFromDir($path) { $images = array(); if ( $img_dir = @opendir($path) ) { while ( false !== ($img_file = readdir($img_dir)) ) { // checks for gif, jpg, png if ( preg_match("/(\.gif|\.jpg|\.png)$/", $img_file) ) { $images[] = $img_file; } } closedir($img_dir); } return $images; } $root = ''; // If images not in sub directory of current directory specify root //$root = $_SERVER['DOCUMENT_ROOT']; $path = 'images/'; // Obtain list of images from directory $imgList = getImagesFromDir($root . $path); $img = getRandomFromArray($imgList); ?> and to show random image i Place the following where i wish the random image to appear: <img src="<?php echo $path . $img ?>" alt="" /> my question is how to place this code in my function first_image?? i need to do something like this, but it doesnt make any sense: if(empty($first_img)){ //Defines a default image $first_img = " <img src="<?php echo $path . $img ?>" alt="" /> this was my thought, if i can mix those 2 normally it should work, right? or maybe there is another way to show random image in the [i] if(empty($first_img)){ //Defines a default image[/i] [b] $first_img = ?
