Write loop sql query from data array (php, mysql) - php

Question

I have a problem with php script.
I have an array, which is generated from form, where $_POST['store'] is an array from jQuery form with functionality to add multiple rows:
Array
(
[client] =>
[darvad] =>
[owca] =>
[ldrive] =>
[store] => Array
(
[product] => Array
(
[0] => 430
[1] => 440
[2] => 430
)
[quantity] => Array
(
[0] => 123
[1] => 1223
[2] => 232
)
[segums] => Array
(
[0] => Mixed park
[1] => Light vehicle
[2] => Trucks
)
[deadline] => Array
(
[0] => 2015-08-04
[1] =>
[2] =>
)
[renewal] => Array
(
[0] => 1
)
)
)
And i need to get values from this array into sql insert statment and loop it.
$sql_rec = "INSERT INTO tsales_funnel_mrecord (product, quantity, segums, deadline)
VALUES (...),(...),(...)....
";
HTML CODE:
<div id="container">
<div id="content" role="main">
<?php
echo "<pre>";
print_r($_POST);
echo "</pre>";
?>
<form action="<?= $_SERVER['REQUEST_URI'] ?>" method="post" id=multiForm>
<label for="client">Klients: *</label><input id="client" type="text" name="client" placeholder="Reg.nr | Pk.kods" value="" /></br>
<label for="selector1">Darījuma vadītājs: *</label>
<select id="selector1" name="darvad" >
<option value="">-Dar. vadītājs-</option>
<?php
$sql = "SELECT Vards_Uzvards, Tables_ID FROM users";
$results = $wpdb->get_results($sql); // return an object, not ARRAY_N
if ($results) {
foreach ($results as $row) {
echo "<option value = '".$row->Tables_ID."'>".$row->Vards_Uzvards."</option>";
}}
echo "</select></br>";
?>
<label for="owcafind">Meklēt OWCA kodu: *</label><input id="owcafind" type="text" name="owca" placeholder="OWCA Kods (8)" value="" /></br>
<label for="ldrive">Mape L diskā:</label><input id="ldrive" type="text" name="ldrive" placeholder="Mape L diskā" value="" /></br>

Answer 1

From your question, it looks like this is what you're after
$itemCount = sizeof($array['store']['product']);
for ($i = 0; $i < $itemCount; $i++) {
$sql_rec = "INSERT INTO tsales_funnel_mrecord (product, quantity, segums, deadline) VALUES ("' . $array['store']['product'][$i] . '", "' . $array['store']['quantity'][$i] . '", "' . $array['store']['segums'][$i] . '", "' . $array['store']['deadline'][$i] . '");";
// Run the sql statement on the database here
}
You'll need to ensure that all user-supplied values are properly escaped before storing in the database.

If Array is called $array, then you can access the arrays values like so;
// product;
$array['store']['product'];
// quantity;
$array['store']['quantity'];
// etc.
Then, if they are to go into a single column (which is bad form and I don't recommend, then you can do something like this;
// product;
$prod_string = '';
foreach ($array['store']['product'] as $key => $prod) {
$prod_string .= $prod;
}
Then you can use $prod_string in your query.
OR, if you need to insert a row for EACH of the keys;
// We use the key from the product loop to get the others;
foreach ($array['store']['product'] as $key => $prod) {
$prod_val = $prod;
$qty_val = !empty($array['store']['quantity'][$key]) ? $array['store']['quantity'][$key] : '';
$seg_val = !empty($array['store']['segums'][$key]) ? $array['store']['segums'][$key] : '';
$dl_val = !empty($array['store']['deadline'][$key]) ? $array['store']['deadline'][$key] : '';
// Right here create your query and insert.
$sql_rec = "INSERT INTO tsales_funnel_mrecord (product, quantity, segums, deadline) VALUES ($prod_val, $qty_val, $seg_val, $dl_val);"
// I'm not sure what library you're using for your db management, so will leave that out.
}
Then you'll have the value of each.
NOTE - I have not checked for clean post values. Ie, sanitized input. Thats outside the scope of this question.

Answer 3

Have done it:
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
// We use the key from the product loop to get the others;
$array = $_POST;
$itemCount = sizeof($array['store']['product']);
// Loop through all $itemCount
$values_string = '';
for ($i = 0; $i < $itemCount; $i++) {
$prod = esc_sql($array['store']['product'][$i]);
$quant = esc_sql($array['store']['quantity'][$i]);
$seg = esc_sql($array['store']['segums'][$i]);
$deadline = esc_sql($array['store']['deadline'][$i]);
$renewal = esc_sql($array['store']['renewal'][$i]);
if ($i < $itemCount - 1) {
$new_str = "('".$prod."','".$quant."','".$seg."','".$deadline."','".$renewal."'),";
} else{
$new_str = "('".$prod."','".$quant."','".$seg."','".$deadline."','".$renewal."');";
}
$values_string .= $new_str;
}
// Run the sql statement on the database here
$sql_rec = "INSERT INTO tsales_funnel_mrecord (Product_type, Vien_skaits, Riska_segums, Deadline, Atjaunojums) VALUES $values_string";
$wpdb->query($sql_rec);
}
