获取HTML <TD> 值

Question

I would like to get the static values from my table data (the tag) and and display it to another page. Should I use jQuery for this or possibly PHP?

Example.php Table:

                                <table width="100%" class="table table-striped table-bordered table-hover display" id="dataTables-example">
                                <thead>
                                    <tr>
                                        <th>Race</th>
                                        <th>Role</th>
                                        <th>2015</th>
                                        <th>2016</th>
                                        <th>2017</th>
                                    </tr>
                                </thead>
                                <tbody>
                                    <tr class="Testing">
                                        <td>BLAH</td>
                                        <td>ANOTHA_BLAH</td>
                                        <td>25</td>
                                        <td>26</td>
                                        <td>27</td>
                                    </tr>
</table>

I tried doing it in PHP similar to

       <form action = "PutTheExampleTableValuesHere.php" method = "post">
           TABLE BLAH BLAH BLAH
       <input type="submit" name="submit" value="View Line Chart">

and using the $_POST function and simply echoing it to the other pages but my logic failed.

Please guide. Thank you!

You may use AJAX to post the whole html code to the other page ( URL ):

$.post(URL, {data: encodeURIComponent($("#dataTables-example").html())})

On the other page( URL ), you can use php's $_POST to get it:

<form action = "PutTheExampleTableValuesHere.php" method = "post">
    <table ...>
        <?php urldecode($_POST['data']) ?>
    </table>
<input type="submit" name="submit" value="View Line Chart">

UPDATE:
@SimoneWalter Then you can compose the data in $.post with the TD values. For example:

data = []
$.each($("#dataTables-example TR"), function(tr){
    // get td values
    tmp = []
    $.each($(tr).find('TD'), function(td){
        tmp.push($(td).html())
    })
    data.push(tmp)
})
// post the data
// data will be something like:
// [['Race', 'Role', '2015', ...], ...]
$.post(URL, {data: data})

Then on the other page:

<form action = "PutTheExampleTableValuesHere.php" method = "post">
    <table ...>
        <thead>
            <?php foreach($_POST['data'] as $tr): ?>
            <tr>
                <?php foreach($tr as $td): ?>
                <td><?php echo $td ?></td>
                <?php endforeach ?>
            </tr>
            <?php endforeach ?>
        </thead>
    </table>
<input type="submit" name="submit" value="View Line Chart">

with the $_POST logic is way more simpler than using javascript/ajax for this solution. Just put your data in some paragraph or similar and give it a name so you can access it from post from another external page that you call in "method" parameter in form. example:

index.php:

  <form action="test.php" method="post">
  <table>
      <td>
          <div id="blah" name="blah" value="blah">BLAH</div>
      </td>
      <td>
          <div id="anoblah" name="anoblah" value="anotherblah">BLAH</div>
      </td>
      <input type="submit" id="test" name="test">
  </table>
  </form>

test.php

   <?php
        if(isset($_POST["test"]))
             echo "td1: ".$_POST["blah"]." td2: ".$_POST["anoblah"];


   ?>

You can probably use jquery to create an array (using input hidden) in the form structure. Then you can read it after the form submit, using $_POST variable.

<script>
$(document).ready(function(){
  $("input[type=submit]").click(function(e) {
    e.preventDefault();
    var form = $("form");
    $(".Testing td").each(function() {
      form.append('<input type="hidden" name="data[]" value="' + $(this).html() + '">');
    });
    form.submit();
  });
});
</script>

This will create an array from the TD values under class "Testing" that you can access over $_POST['data'] (type Array).

<?php 
if(isset($_POST['data'])) {
  foreach($_POST['data'] as $key=>$val) {
    echo $key.' = '.$val.'<br>';
  }
}
?>
