Adastra Posted November 20, 2006 Share Posted November 20, 2006 Hi guys, I'm trying to write a small gallery script which gives the possibility to upload a number of 1-10 files at once - first thing the user does is pick the number of files to upload, then he is directed to the upload form(s). Now my problem is that I don't know how to process the multiple files at once - there are 4 fields for each photo, the file itself, a title, a description and the gallery id. All of that is inserted into a DB after the images have been resized and uploaded - how do I do both of those things for multiple files at once? It must be something with for or foreach, but I have no idea how to use it with multiple files AND multiple fields to be post at once. The affected part is the add action. Any help would be very appreciated :)This is my file: [code=php:0]if ($_POST['action'] == "add") { foreach () { //__ photos in dir ablegen _______________________________________ $ul_photo = $_FILES['photo']['tmp_name']; $src = imagecreatefromjpeg($ul_photo); list($width,$height) = getimagesize($ul_photo); $newwidth = 550; $newheight = ($height/$width)*$newwidth; $tmp = imagecreatetruecolor($newwidth,$newheight); imagecopyresampled($tmp,$src,0,0,0,0,$newwidth,$newheight,$width,$height); $filename = $dirpath.$gal_id."/". $_FILES['photo']['name']; imagejpeg($tmp,$filename,100); #__ thumb _________________________________________________________ $ul_thumb = $_FILES['photo']['tmp_name']; $srcthumb = imagecreatefromjpeg($ul_thumb); list($widththumb,$heightthumb) = getimagesize($ul_thumb); $newwidththumb = 100; $newheightthumb = ($heightthumb/$widththumb)*$newwidththumb; $src_top = ($src_height / 2) - ($dst_height / 2); $src_left = ($src_width / 2) - ($dst_width / 2); $tmpthumb = imagecreatetruecolor($newwidththumb,$newheightthumb); imagecopyresampled($tmpthumb,$srcthumb,0,0,$src_top,$src_left,$newwidththumb,$newheightthumb,$widththumb,$heightthumb); $thumbname = $dirpath.$gal_id."/zth_".$titlesuf . $_FILES['photo']['name']; imagejpeg($tmpthumb,$thumbname,100); #___________________________________________________________________ imagedestroy($src); imagedestroy($tmp); imagedestroy($srcthumb); imagedestroy($tmpthumb); $gal = addslashes($_POST['gal_id']); $photo = $_FILES['photo']['name']; $title = addslashes($_POST['title']); $description = addslashes($_POST['description']); $sql = "INSERT INTO $gal_photos (gal,photo,title,description) VALUES ('$gal','$photo','$title','$description')"; $query = mysql_query($sql) or die("MySQL Error: <br /> {$sql} <br />". mysql_error()); $num = mysql_affected_rows(); if($num > 0) { echo "<span class='result'>New Photo successfully added!</span>"; echo "<br /><img src='../galleries/".$gal."/zth_".$photo."' />"; } else { echo "Error: ".mysql_error(); } } #foreach} elseif ($_GET['action'] == "listforms") {?><strong>Post New Photos</strong><br /><br /><form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>" enctype="multipart/form-data"><input type="hidden" name="MAX_FILE_SIZE" value="649760" /> <? for ($x=0;$x<$_GET['num'];$x++) { ?> <div class='uploadbox'> Associated Gallery <?=$x + 1?>: <br /> <? $selgal_sql = "SELECT * FROM $gal_galleries ORDER BY id DESC"; $selgal_result = mysql_query($selgal_sql) or print ("Unable to select data.<br />".$selgal_sql."<br />".mysql_error()); $selgal_num = mysql_num_rows($selgal_result); if ($selgal_num > 0) { echo "<select name='gal_id[]'>"; while ($selgal_row = mysql_fetch_array($selgal_result)) { $selgal_id = $selgal_row["id"]; $selgal_title = $selgal_row["title"]; echo "<option value='".$selgal_id."'>".$selgal_id.": ".$selgal_title."</option>"; } echo "</select>"; } else { echo "<a href='gal_galleries.php'>Please create a new gallery to post photos!</a>"; } ?> <br /> <br /> Photo File <?=$x + 1?>: <br /> <input type='file' name='photo[]' size='50' /> <input type="hidden" name="thumb[]" value="<?

Adastra Posted November 21, 2006 Author Share Posted November 21, 2006 Cool, thanks a lot, but right now I get this incredibly long site of error messages when I try to post multiple photos...:I've looked in the Database, it created new entries for each, but it didn't insert anything except for the word "Array" in the first row. All other rows are blank (expect for the id of course).[quote]Warning: Division by zero in /www/htdocs/gallery/gal_postphotos2.php on line 15Warning: imagecreatetruecolor()
