How to select files from a grid using a checkbox to add to a zip to download

Question

I have a directory viewer that generates rows based on the files present in the directory that are displayed on the grid. I'm trying to add checkboxes that, when checked, will add the selected files to a zip archive. Currently my code is this

<div id="directory-list-header">
            <div class="row">
                <div class="col-md-7 col-sm-6 col-xs-10">File</div>
                <div class="col-md-1 col-sm-2 col-xs-2 text-right">Size</div>
                <div class="col-md-2 col-sm-2 hidden-xs text-right">Last Modified</div>
                <div class="col-md-2 col-sm-2 col-xs-2 text-right">Select</div>
            </div>
        </div>

        <ul id="directory-listing" class="nav nav-pills nav-stacked">

            <?php foreach($dirArray as $name => $fileInfo): ?>
                <li data-name="<?php echo $name; ?>" data-href="<?php echo $fileInfo['url_path']; ?>">
                    <a href="<?php echo $fileInfo['url_path']; ?>" class="clearfix" data-name="<?php echo $name; ?>">


                        <div class="row">
                            <span class="file-name col-md-7 col-sm-6 col-xs-9">
                                <i class="fa <?php echo $fileInfo['icon_class']; ?> fa-fw"></i>
                                <?php echo $name; ?>
                            </span>

                            <span class="file-size col-md-1 col-sm-2 col-xs-3 text-right">
                                <?php echo $fileInfo['file_size']; ?>
                            </span>

                            <span class="file-modified col-md-2 col-sm-2 hidden-xs text-right">
                                <?php echo $fileInfo['mod_time']; ?>
                            </span>

                            <span class="selected col-md-2 col-sm-2 col-xs-1 text-right">
                                <form method="get">
                                    <input type="checkbox" name="selected[]" value="<?php echo $fileInfo['url_path']; ?>">
                                </form>
                            </span>
                        </div>

I added the <span> tag and I was thinking that I should add any files that are checked to an array, then send that array to a zip using ZipArchive() and serving it to the client via a stream, however I'm not sure how the code would look for the checkbox logic since this is my first foray into HTML/PHP. Any help would be appreciated, I have the user interface squared away, it's just a matter of getting the background working

Create array[] from $_POST['files_names'] like here PHP access all $_POST[] variables into an array? and from that array create zip like here Download multiple files as a zip-file using php 6 answer.

Hmm, I'll have to dig into $_POST and see if I can take advantage of it – Tadhg Mar 29 '17 at 18:06

php has a class that does it.

Learn about it here http://php.net/manual/en/class.ziparchive.php.

The code bellow can solve your issue;

<?php
  $zip = new ZipArchive;

  function addFileToZip($aFileZipName, $aFileName, $fileContent){

    if ($zip->open($aFileZipName) === TRUE) {

      $zip->addFromString($aFileName, $fileContent);

      $zip->close();

      return true;
    } else {

      return false;  

    }
  }
?>

if this explanation couldn't help you, please, post your complete code. By the way, consider use a more elegant way to produce your HTML code, like angular or jquery.

Hello, this appears to be a generic `ZipArchive()` answer that doesn't really help my issue (since i understand `ZipArchive()`). Thanks though! — Tadhg, Mar 29 '17 at 18:05
