DeX Posted December 15, 2010 Share Posted December 15, 2010 Here's my PHP form code: <form method='POST' action="<?php basename($_SERVER['PHP_SELF']);?>" onSubmit="return stripInputBoxes(1)"> <?php echo "<div id = 'purchaseOrderRow1' style = 'display:none;border: 1px solid black;'>"; echo $integrityBuildingProductsPDF; echo '<input type = "hidden" id = "pdf1" value = "" name = "pdf1" />'; echo '<button name = "savePurchaseOrder" type = "submit">Save Purchase Order</button>'; echo "</div>"; ?> </form> Here's my Javascript: function stripInputBoxes(pdfNumber) { if (!document.getElementsByTagName) return; for (i = 0; i < document.getElementById('tableBody').getElementsByTagName('tr').length - 3; i++) { document.getElementById(i).parentNode.innerHTML = document.getElementById(i).value; } document.getElementById("pdf" + pdfNumber).value = "ljkasdkljf"; return true; } Will this set the value of the hidden variable? I'm trying to echo the value of $_POST['pdf1'] but it comes out to nothing when the page reloads. How do I do this? What I'm trying to do here is display a purchase order on the screen and the user can edit the quantities in the purchase order. They click SAVE to save the new updated quantities and it auto generates a PDF that's saved on the server with those new quantities. The problem is I need to run the stripInputBoxes function to take the <input> tags out of the HTML code before creating the PDF because the PDF generator doesn't recognize the tags.
