PHP - Image Chosen Does Not Get Replaced

Hi guys. As I am new to PHP, I have a question.

Necessarily, this need not be done in php, if you have something in html or js that can be done, let me know! Well, I have a form where you enter information like name, city, phone and product option. These product options include real estate and auto options. By clicking submit (to submit form), I need to direct the visitor to their chosen product option.

For example, when I filled out the form I chose 'real estate'. When I clicked submit, it went to a page where the real estate-only content appeared.

Note: I already have this code ready below and it already directs the information to the database. However, I don't know how to make him redirect to the customer, the product option he chose.

      <form action="simulador.php" method="post" name="dados" id="dados" onSubmit="return validaform()">
            <div class="col-md-5 esquerda">
                           Selecione o bem<br/>
                           <select name="tipo" type="text" class="contat3" placeholder="Selecione o bem">
                           <option value="Im�vel""

                           <option value="Autom�vel""

            </div>         
       </form>

This is the code that I'm using for a shopping cart in order to update the quantity if the same product id is chosen. 

$cart_items is a two-dimensional session array composed of the id session array and the quantity session array. While looping through $cart_items, I create a temporary array $temp_array so that I can execute some logic on the array without changing the normal output. $temp_array is the $cart_items array without the last items which would be the $_REQUEST id and the $_REQUEST quantity. So the two $_REQUESTs are popped off with array_pop and then the remaining $_SESSIONs are compared to the $_REQUEST id with 

$j = array_search($_REQUEST["element_id_$i"], $temp_array);
$j is now the key that corresponds to the id in $temp_array where the $_REQUEST id has been found. 

if( $j==$temp_array[$i]) 

If $j is the key of the item in $temp_array, then the $_REQUEST is unset and the quantities for the item are added together. 

There are two problems with this code. First of all the var_dump of the $temp_array is always an empty array but I am expecting to get an array with just the last element popped off. Secondly, 
I get the error "Undefined offset" for the $i variable in this line of the code: if( $j==$temp_array[$i]) 
 

foreach($cart_items as $item) {
foreach($item["id"] as $key => $val) {
foreach($item["quantity"] as $i => $value) {
    if ($key == $i){
    
$temp_array = $cart_items;
$array = array_pop($temp_array);
var_dump($temp_array);

if (isset($_REQUEST["element_id_$i"]) && isset($_REQUEST["quantity_$i"])&& isset($value)){
    
$j = array_search($_REQUEST["element_id_$i"], $temp_array);
if( $j==$temp_array[$i]) {
echo "<b>SAME PRODUCT ADDED</b>";
$value += $_REQUEST["quantity_$i"];
unset($_REQUEST["element_id_$i"]);
}}}}}}

<?php
$str = 'some blob ~abc~ followed by ~def~';

$arr_orig = array(
	'~abc~',
	'~def~'
);

$arr_new  = array(
	'value~def~',
	'blah'
);

echo str_replace( $arr_orig, $arr_new, $str );
?>

        $validextensions = array("jpeg", "jpg", "png");  //Extensions which are allowed
        $ext = explode('.', basename($_FILES['file']['name'][$i]));//explode file name from dot(.) 
        $file_extension = end($ext); //store extensions in the variable

        $new_image_name = md5(uniqid()) . "." . $ext[count($ext) - 1];
		$target_path = $target_path . $new_image_name;//set the target path with a new name of image
