 am new to PHP and MySQL and I will really need some assistance. Whenever I fill in all the information and submit my form, It successfully adds all information to the database. But the only issue is at the level of the images. When I upload two or more images, it only adds one image to the database and my upload file.

Any Idea on what's wrong?

What I have tried:

Here is my PHP CODE
public function adInsert($data, $file){
      $title = mysqli_real_escape_string($this->db->link, $data['title']);
       $catId = mysqli_real_escape_string($this->db->link, $data['catId']);
       $subcatId = mysqli_real_escape_string($this->db->link, $data['subcatId']);
       $priceformat = mysqli_real_escape_string($this->db->link, $data['priceformat']);
       $price = mysqli_real_escape_string($this->db->link, $data['price']);
       $regionId = mysqli_real_escape_string($this->db->link, $data['regionId']);
       $state = mysqli_real_escape_string($this->db->link, $data['state']);
       $description = mysqli_real_escape_string($this->db->link, $data['description']);

       if(count($file['images']['name']) > 0){
           for ($i = 0; $i < count($file['images']['name']); $i++) {//loop to get individual element from the array

               $permited  = array('jpg', 'jpeg', 'png', 'gif');
               $file_name = $file['images']['name'][$i];
               $file_size = $file['images']['size'][$i];
               $file_temp = $file['images']['tmp_name'][$i];

               $div = explode('.', $file_name);
               $file_ext = strtolower(end($div));
               $unique_image = substr(md5(time()), 0, 10).'.'.$file_ext;
               $uploaded_image = "../uploads/".$unique_image;

               if($title == "" || $catId == "" || $subcatId == "" || $priceformat == "" || $price == ""  || $regionId == "" || $file_name == "" || $state == "" || $description == ""){
                   $msg = "<span class='error'>Fields must not be empty!</span>";
                   return $msg;

               } elseif ($file_size >1048567) {
                    echo "<span class='error'>Image Size should be less then 1MB!

               } elseif (in_array($file_ext, $permited) === false) {
                   echo "<span class='error'>You can upload only:-".implode(', ', $permited)."</span>";

               } else{
                   move_uploaded_file($file_temp, $uploaded_image);
                   $query = "INSERT INTO ads(title, catId, subcatId, priceformat, price, regionId, images, state, description) VALUES('$title','$catId','$subcatId', '$priceformat', '$price','$regionId', '$uploaded_image', '$state', '$description')";
                   $inserted_row = $this->db->insert($query);

                               $msg = "<span class='success'> Your ad has been uploaded successfully. </span>";
                               return $msg;
                           } else{
                               $msg = "<span class='error'> Sorry! Your offer is not added! Try again later. </span>";
                               return $msg;

Here is My form page
		$ad = new Ad();
        if($_SERVER['REQUEST_METHOD'] == 'POST' && isset($_POST['create'])){
        $insertAd = $ad->adInsert($_POST, $_FILES);


<form action="" method="post" class="ad-form"  enctype="multipart/form-data" data-parsley-validate >
		 <div class="form-fields-content">

	 <label for="region">Location | Region</label>

			$getRegion = $region->getAllRegion();
					 while($result = $getRegion->fetch_assoc()){

             <?php } } ?>

	<label for="images[]">Images*</label>                   
    <input type="file" id="Photofile" name="images[]" required="required" data-parsley-required-message="Please Upload at least one photo" multiple />
       <label for="condition">Condition</label>

      <input type="submit" name="create" value="Create Post" class="button" />

And here is the Javascript I use for Images preview
<script type="text/javascript">
	var count=0;
	function handleFileSelect(evt) {
		var $fileUpload = $("input#Photofile[type='file']");
		if (parseInt($fileUpload.get(0).files.length) > 4 || count>3) {
			alert("You can only upload a maximum of 3 photos");
			return false;
		var files =;
		for (var i = 0, f; f = files[i]; i++) {
			if (!f.type.match('image.*')) {
			var reader = new FileReader();

			reader.onload = (function (theFile) {
				return function (e) {
					var span = document.createElement('span');
					span.innerHTML = ['<img class="thumb mrm mts" src="',, '" title="', escape(, '"/><span class="remove_img_preview"></span>'].join('');
					document.getElementById('list').insertBefore(span, null);


	$('#list').on('click', '.remove_img_preview',function () {
        //this is not working...
        var i = array.indexOf($(this));
        if(i != -1) {
            array.splice(i, 1);
        // tried this too:
        //$(this).parent('span').splice( 1, 1 );

$unique_image = substr(md5(time()), 0, 10).'.'.$file_ext;
Your image names are probably not unique because time() returns a second based value (see PHP: time - Manual[^]).

You should also not truncate the MD5 hash has because that may also result in duplicates.

I suggest to use PHP: tempnam - Manual[^] instead.

@jochen Oh I see. So is the format like this $unique_image = substr(tempnam(), 0, 10).'.'.$file_ext;
Jochen Arndt 16-Feb-18 8:15am    
No. See the provided link to the PHP documentation. You have to pass the directory path (resolved full path for "../uploads"). The returned string is a full path that must not be shortened by using substr().

Note also that the returned path has no image file extension. You might append that but it will again break the uniqueness because tempnam() ensures only that the returned name is unique. When doing so you should also delete the returned file name because tempnam() has already created the file with zero size.
