Create a Zip File Using PHP and Download Multiple Files

DOWNLOAD

Today i am sharing how to create a zip file of multiple files using PHP and download that zip file on click. For this purpose i will need a folder where all files are available which can be selected and downloaded. I will also create a single php page which contain the following scripts.

HTML

Create a simple PHP page and copy paste the below form.

1 2 3 4 5 6 7 8 9 10 11

<form name="zips" action="" method="post"> <input type="checkbox" id="checkAll" /> <label>Select All</label><br /> <input class="chk" type="checkbox" name="files[]" value="SampleFile.pdf"/> <label>PDF File</label><br /> <input class="chk" type="checkbox" name="files[]" value="SampleFile.docx"/> <label>Word File</label><br /> <input class="chk" type="checkbox" name="files[]" value="AllPHPTricks.png"/> <label>Image File</label><br /> <input type="submit" id="submit" name="createzip" value="Download All Seleted Files" > </form>

jQuery

Add the following script in footer of web page. Don’t forget to add jQuery library before this script.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

$('#submit').prop("disabled", true); $("#checkAll").change(function () {       $("input:checkbox").prop('checked', $(this).prop("checked"));   $('#submit').prop("disabled", false);   if ($('.chk').filter(':checked').length < 1){ $('#submit').attr('disabled',true);} });   $('input:checkbox').click(function() {         if ($(this).is(':checked')) { $('#submit').prop("disabled", false);         } else { if ($('.chk').filter(':checked').length < 1){ $('#submit').attr('disabled',true);} } });

As you can see above that when you click on select all, all checkboxes are checked or unchecked. You can see my tutorial about how to select deselect all checkboxes using jquery.

PHP

Copy paste the below PHP script in the top of web page. When someone submit form first we are checking if files array is set or not, then we are creating zip file and downloading that file.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45

<?php if(isset($_POST['files'])) { $error = ""; //error holder if(isset($_POST['createzip'])) { $post = $_POST; $file_folder = "files/"; // folder to load files if(extension_loaded('zip')) { // Checking ZIP extension is available if(isset($post['files']) and count($post['files']) > 0) { // Checking files are selected $zip = new ZipArchive(); // Load zip library $zip_name = time().".zip"; // Zip name if($zip->open($zip_name, ZIPARCHIVE::CREATE)!==TRUE) { // Opening zip file to load files $error .= "* Sorry ZIP creation failed at this time"; } foreach($post['files'] as $file) { $zip->addFile($file_folder.$file); // Adding files into zip } $zip->close(); if(file_exists($zip_name)) { // push to download the zip header('Content-type: application/zip'); header('Content-Disposition: attachment; filename="'.$zip_name.'"'); readfile($zip_name); // remove zip file is exists in temp path unlink($zip_name); }   } else $error .= "* Please select file to zip "; } else $error .= "* You dont have ZIP extension"; } } ?>
