Good Day! :)
I created a chained select using php and jQuery like on this page http://www.yourinspirationweb.com/en/how-to-create-chained-select-with-php-and-jquery/ and I created a javascript to add and delete select tags I get it somewhere on the internet but what happening is when I choose a category on the first line everything on the subcategory will be enabled and also on the product description. Just like this https://i.sstatic.net/H9nfb.jpg
this is my code:
<html>
<head>
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$("select#type").attr("disabled", "disabled");
$("select#category").change(function() {
$("select#type").attr("disabled", "disabled");
$("select#type").html("<option>wait...</option>");
var id = $("select#category option:selected").attr('value');
$.post("select_type.php", {
id: id
}, function(data) {
$("select#type").removeAttr("disabled");
$("select#type").html(data);
});
});
$("select#desc").attr("disabled", "disabled");
$("select#type").change(function() {
$("select#desc").attr("disabled", "disabled");
$("select#desc").html("<option>wait...</option>");
var id = $("select#type option:selected").attr('value');
$.post("select_desc.php", {
id: id
}, function(data) {
$("select#desc").removeAttr("disabled");
$("select#desc").html(data);
});
});
$("form#select_form").submit(function() {
var cat = $("select#category option:selected").attr('value');
var type = $("select#type option:selected").attr('value');
var descr = $("select#desc option:selected").attr('value');
if (cat > 0 && type > 0 && descr > 0) {
var result = $("select#desc option:selected").html();
$("#result").html('your choice: ' + result);
} else {
$("#result").html("you must choose two options!");
}
return false;
});
});
</script>
<script type="text/javascript">
function addRow(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
var colCount = table.rows[0].cells.length;
for (var i = 0; i < colCount; i++) {
var newcell = row.insertCell(i);
newcell.innerHTML = table.rows[1].cells[i].innerHTML;
//alert(newcell.childNodes);
switch (newcell.childNodes[0].type) {
case "text":
newcell.childNodes[0].value = "";
break;
case "checkbox":
newcell.childNodes[0].checked = false;
break;
case "select-one":
newcell.childNodes[0].selectedIndex = 0;
break;
}
}
}
function deleteRow(tableID) {
try {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
for (var i = 0; i < rowCount; i++) {
var row = table.rows[i];
var chkbox = row.cells[0].childNodes[0];
if (null != chkbox && true == chkbox.checked) {
if (rowCount <= 2) {
alert("Cannot delete all the rows.");
break;
}
table.deleteRow(i);
rowCount--;
i--;
}
}
} catch (e) {
alert(e);
}
}
</script>
</head>
<body>
<?php include "select.class.php"; ?>
<form id="select_form">
<input type="button" value="Add" onclick="addRow('tableID')" />
<input type="button" value="Delete" onclick="deleteRow('tableID')" />
<table id="tableID">
<tr>
<td></td>
<td>Category</td>
<td>SubCategory</td>
<td>Product Description</td>
</tr>
<tr>
<td>
<input type="checkbox" name="chkbox[]" />
</td>
<td>
<select id="category" name="category[]">
<?php echo $opt->ShowCategory(); ?></select>
</td>
<td>
<select id="type" name="type[]">
<option value="0">choose...</option>
</select>
</td>
<td>
<select id="desc" name="desc[]">
<option value="0">choose...</option>
</select>
</td>
</tr>
</table>
<input type="submit" value="confirm" />
</form>
<div id="result" name="result[]"></div>
</body>
</html>
Hope anyone could help me. :)
