If using JavaScript is an option and you want to avoid nesting tables, include jQuery and try the following method.
First, you'll have to give each row a unique id like so:
<table>
<tr id="idrow1"><td> ADD AS MANY COLUMNS AS YOU LIKE </td><td><button onclick="submitRowAsForm('idrow1')">SUBMIT ROW1</button></td></tr>
<tr id="idrow2"><td> PUT INPUT FIELDS IN THE COLUMNS </td><td><button onclick="submitRowAsForm('idrow2')">SUBMIT ROW2</button></td></tr>
<tr id="idrow3"><td>ADD MORE THAN ONE INPUT PER COLUMN</td><td><button onclick="submitRowAsForm('idrow3')">SUBMIT ROW3</button></td></tr>
</table>
Then, include the following function in your JavaScript for your page.
<script>
function submitRowAsForm(idRow) {
form = document.createElement("form"); // CREATE A NEW FORM TO DUMP ELEMENTS INTO FOR SUBMISSION
form.method = "post"; // CHOOSE FORM SUBMISSION METHOD, "GET" OR "POST"
form.action = ""; // TELL THE FORM WHAT PAGE TO SUBMIT TO
$("#"+idRow+" td").children().each(function() { // GRAB ALL CHILD ELEMENTS OF <TD>'S IN THE ROW IDENTIFIED BY idRow, CLONE THEM, AND DUMP THEM IN OUR FORM
if(this.type.substring(0,6) == "select") { // JQUERY DOESN'T CLONE <SELECT> ELEMENTS PROPERLY, SO HANDLE THAT
input = document.createElement("input"); // CREATE AN ELEMENT TO COPY VALUES TO
input.type = "hidden";
input.name = this.name; // GIVE ELEMENT SAME NAME AS THE <SELECT>
input.value = this.value; // ASSIGN THE VALUE FROM THE <SELECT>
form.appendChild(input);
} else { // IF IT'S NOT A SELECT ELEMENT, JUST CLONE IT.
$(this).clone().appendTo(form);
}
});
form.submit(); // NOW SUBMIT THE FORM THAT WE'VE JUST CREATED AND POPULATED
}
</script>
So what have we done here? We've given each row a unique id and included an element in the row that can trigger the submission of that row's unique identifier. When the submission element is activated, a new form is dynamically created and set up. Then using jQuery, we clone all of the elements contained in <td>
's of the row that we were passed and append the clones to our dynamically created form. Finally, we submit said form.
