How do i store data from jquery to a 2D array in php without ajax?
Question
The jquery code makes up a table and sends "hide1" and "hide2" number of rows and columns to php, where it should be stored into the database.
$(document).ready(function(){
var i=4;
var ctr=0;
var col=0;
var ctr2=0;
var col=3;
var ctr1=0;
var i2=1;
$("#add").click(function(){
$("table").append('<tr id="'+ctr1+'"></tr>');
for(var j=1;j<=col;j++){
$("#"+ctr1).append('<td><input type="text" name="n'+(i++)+'"></td>');
}
ctr1++;
$("#h1").val(ctr1);
});
$("button").click(function(){
ctr2++;
col++;
$("tr").append('<td><input type="text" name="c'+(i2++)+'"></td>');
$("#h2").val(ctr2);
});
});
And here is the php code.
<?php
if(isset($_REQUEST['sub']))
{
$cr=$_GET['hide1'];
echo "No. of added rows=".$cr."<br>";
$cc=$_GET['hide2'];
echo "<br> No. of added columns=".$cc;
$data[$cr][$cc];
}
?>
<html>
<title> BIA </title>
<head>
<script type="text/javascript" src="http://code.jquery.com/jquery- 2.1.4.min.js"></script>
<script type="text/javascript" src="http://localhost/1.js"></script>
</head>
<fieldset>
<legend>Enter text</legend>
<form method="GET" action="#">
<table border="1">
<tr>
<td><input type="text" name="n1"></td>
<td> <input type="text" name="n2"></td>
<td> <input type="text" name="n3"></td>
</tr>
</table>
<input type="hidden" name="hide1" id="h1">
<input type="hidden" name="hide2" id="h2">
<input type="submit" name="sub" value="SEND">
<input type="submit" name="next" value="Enter More">
<input type="button" id="add" value="add row">
</form>
<button>Add Column</button>
</fieldset>
</body>
</html>
I am not able to figure out how to make a 2D array get the elements returned by jquery.

Use indexes in input names, to make array. For example, if you need simple array, like [1,2,3,4,5,6] the name in inputs must be like:
<tr><td><input type="text" name="n[0]"></td></tr>
<tr><td><input type="text" name="n[1]"></td></tr>
<tr><td><input type="text" name="n[2]"></td></tr>
If you need 2D array, like [[1,2,3],[4,5,6],[7,8,9]] the name in inputs must be like:
<tr><td><input type="text" name="n[0][1]"></td></tr>
<tr><td><input type="text" name="n[0][2]"></td></tr>
<tr><td><input type="text" name="n[0][3]"></td></tr>
<tr><td><input type="text" name="n[1][1]"></td></tr>
<tr><td><input type="text" name="n[1][2]"></td></tr>
<tr><td><input type="text" name="n[1][3]"></td></tr>
