For some reason I cannot set the loop time because I am generating the form dynamically using jQuery. I have done some research for the topic,normally will use foreach
to loop for all valid fields but I'm not sure how to do these:
<form action="testing.php" method="post" >
<input type="text" name="product[1][name]" value="product1"/>
<input type="text" name="product[1][color][]" value="product1color1"/>
<input type="text" name="product[1][color][]" value="product1color2"/>
<input type="text" name="product[1][color][]" value="product1color3"/>
<input type="text" name="product[2][name]" value="product2"/>
<input type="text" name="product[2][color][]" value="product2color1"/>
<input type="text" name="product[3][name]" value="product3"/>
<input type="text" name="product[3][color][]" value="product3color1"/>
<input type="text" name="product[4][name]" value="product4"/>
<input type="text" name="product[4][color][]" value="product4color1"/>
<input type="submit" />
And my testing code ended up like these, it is not working .=(
<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$product=$_POST['product'];
//store everything that start with product into array
foreach($product as $key){
//loop for product.1 product.2 and so on.....
//echo name of current product
echo $product[$key]['name'];
foreach($product[$key]['color'][] as $point){
echo $point;
}//loop for every single available color field
}//end of product loop
}// end of post request
?>
The statement $product = $_POST['product'];
will arrange the data from your HTML form into a multidimensional array that looks like this:
Array(
1 => Array(
"name" => "product1",
"color" => Array(
0 => "product1color1",
1 => "product1color2",
2 => "product1color3"
)
),
2 => Array(
"name" => "product2",
"color" => Array(
0 => "product2color1"
)
),
...
)
To iterate this array, you need to do:
foreach($product as $key1 => $prd) {
echo $prd['name'];
foreach($prd['color'] as $key2 => $point) {
echo $point;
}
}
On each pass, $key1
will contain the array keys (1, 2, 3) whereas $prd
will contain the item associated with that key ( $product[1]
, $product[2]
, $product[3]
). You can omit the $key =>
portion altogether if necessary. Likewise for the inner loop.
Your code should be like this
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$product=$_POST['product'];
//print_r($_POST['product']);
//store everything that start with product into array
for($i=0; $i<count($product); $i++){
// foreach($product as $key){
//loop for product.1 product.2 and so on.....
echo "<br/> ".$product[$i]['name'];
for($j=0; $j<count($product[$i]['color']); $j++){
// foreach($product[$key]['color'][] as $point){
echo "<br/> ".$product[$i]['color'][$j];
}//loop for every single available color field
}//end of product loop
}// end of post request
