Everthing here works fine except that in the saved file it doesn't give me the whole string. Just one of the IDs (There are multiple on the page).

Not sure how get "all of the IDs and Content" in the $.ajax()

What am I doing wrong?

Have got this jquery:

$('a#exportPage').on('click',function(){
var contentMap = {};
$('[id^="appendHeading"]').each(function(){
    contentMap[this.id] = $(this).text();
});
for(id in contentMap)
    $("#PrintIds").append("ObjectID:" + id + "Content:" + contentMap[id]);

$.ajax({
  url: "post.php",
  type: "post",
  data: { 
      objectID: id,
      content: contentMap[id]
      },
      success: function(){
      alert("success");
  },
  error:function(){
      alert("failure");
  }   
 }); 
});

And this PHP:

<?php
if ($_POST['objectID'] || $_POST['content']) {
$myFile = "test.css";
$stringData = $_POST['objectID'] || $_POST['content'];
file_put_contents($myFile,$stringData);
}
?>
