Problem with my registration form. Not inserting second query - php

First of all sorry for my language. I am a doing a shopping cart application for my assignment for college. I have a problem with registration for. The problem is that it is inserting the first query
$addsql = "INSERT INTO customers(forename, surname, add1, add2, add3, postcode, phone, email, registered)
VALUES('"
. strip_tags(addslashes($_POST['forenameBox'])) . "', '"
. strip_tags(addslashes($_POST['surnameBox'])) . "', '"
. strip_tags(addslashes($_POST['add1Box'])) . "', '"
. strip_tags(addslashes($_POST['add2Box'])) . "', '"
. strip_tags(addslashes($_POST['add3Box'])) . "', '"
. strip_tags(addslashes($_POST['postcodeBox'])) . "', '"
. strip_tags(addslashes($_POST['phoneBox'])) . "', '"
. strip_tags(addslashes($_POST['emailBox'])) . "',
1)";
mysql_query($addsql);
and it does not insert the second one.
$customer_id = mysql_insert_id(); // Gets The id Of Last MySql INSERT Query
$insert_query = 'INSERT INTO logins (
username,
password,
customer_id
)
VALUES
(
"' . $_POST['userregBox'] . '",
"' . md5($_POST['passregBox']) . '",
"' . $customer_id . '",
)';
mysql_query($insert_query);
header("Location: " . $basedir . "login.php?ok=1");
I tried different approaches with no result. I am using Xammp.

You have an extra comma.
Change
"' . $customer_id . '",
to
"' . $customer_id . '"
in your INSERT INTO LOGINS query.

PHP update table in MySQL not working

My php won't update my products table. I know my GET request worked as I tested it with echo to display the id. I am confused as to how I can get it to work? I think it may be something to do with the form action= on my form but I am confused! Can someone please help?
<?php
// Connection file
require 'db.php';
if (((!empty($_GET["mode"])) && (!empty($_GET["id"]))) && ($_GET["mode"] == "update")) {
// If update
echo $_GET['id'];
if (isset($_POST["updateSubmit"])) {
$pName = $_POST["updateProductName"];
echo $pName;
$query = "UPDATE products "
. "SET p_name = '" . $_POST["updateProductName"] . "', "
. "p_type = '" . $_POST["updateProductType"] . "', "
. "p_desc = '" . $_POST["updateProductDesc"] . "', "
. "p_price = '" . $_POST["updateProductPrice"] . "', "
. "p_stock = " . $_POST["updateProductStock"] . ", "
. "WHERE id=" . $_GET['id'] . ";";
$result = mysqli_query($conn, $query);
}
}
?>
<div>
<form id="updateForm" name="updateForm" action="<?php echo "?mode=update&id=" . $productDetails["id"]; ?>" method="post">
<label>Product name:</label><br>
<input type="text" name="updateProductName"><br>
<label>Product type</label><br>
<select name="updateProductType">
<option value="Jackets/coats">Jackets/coats</option>
<option value="Accessories">Accessories</option>
<option value="Shirts">Shirts</option>
<option value="Jeans">Jeans</option>
<option value="Trousers">Trousers</option>
<option value="Shoes">Shoes</option>
<option value="Suits">Suits</option>
</select>
<p>Product description:</p>
<textarea name="updateProductDesc" rows="10" cols="30"></textarea><br>
<label>Product price:</label><br>
<input type="text" name="updateProductPrice"><br>
<label>Stock level:</label><br>
<input type="text" name="updateProductStock"><br>
<input type="submit" name="updateSubmit" value="Submit">
</form>
</div>
<?php
?>
I think the problems are misusing of ' in one or both of these lines
. "p_price = '" . $_POST["updateProductPrice"] . "', "
. "p_stock = " . $_POST["updateProductStock"] . ", "
If the type is string you need to use ' as you used in p_price otherwise if it is float or int you should not use ' as you did for p_stock.
It seems you used wrong for these two field. Since the p_price would be float and p_stock is string.
. "p_price = " . $_POST["updateProductPrice"] . ", "
. "p_stock = '" . $_POST["updateProductStock"] . "' , "
There are two issues with your query...
You Have one extra comma before the Where Section and your missing delimeters on p_stock.
Should be:
"p_stock = '" . $_POST["updateProductStock"] . "' "
and
. "WHERE id='" . $_GET['id'] . "'";

Thanks!
This has nothing to do with OpenCart itself, it is about basic PHP. You need to loop through all the posted values and insert one set of values at a time.
It should be like this:
$values_count = count($data['forma']);
for ($i = 0; $i < $values_count; $i++) {
$query = $this->db->query("INSERT INTO `" . DB_PREFIX . "order` SET"
. " customer_id = " . (int)$data['customer_id']
. ",forma = '" . $this->db->escape($data['forma'][$i])
. "', linkto = '" . $this->db->escape($data['linkto'][$i])
. "', description = '" . $this->db->escape($data['description'][$i])
. "', cvet = '" . $this->db->escape($data['cvet'][$i])
. "', sizes = '" . $this->db->escape($data['sizes'][$i])
. "', counts = " . (int)$data['counts'][$i]
. ", tcena = " . (int)$data['tcena'][$i]
. ", sposob = '" . $this->db->escape($data['sposob'][$i])
. "', delivery_usa = '" . $this->db->escape($data['delivery_usa'][$i])
. "', hint = '" . $this->db->escape($data['hint'][$i])
. "', novapochta = '" . $this->db->escape($data['novapochta'][$i])
. "', customer_group_id = " . (int)$data['customer_group_id'] [$i]
. ", firstname = '" . $this->db->escape($data['firstname'][$i])
. "', lastname = '" . $this->db->escape($data['lastname'][$i])
. "', email = '" . $this->db->escape($data['email'][$i])
. "', telephone = '" . $this->db->escape($data['telephone'][$i])
. "', date_added = NOW()"
. ", order_status_id = 1");
$new_order_id = $this->db->getLastId();
}
Integer values does not need to be escaped with '1' when You typecast them to (int).
You form fields are arrays like : forma[], linkto[] which cannot be used with $this->db->escape().
Please echo the variable $value within the loop foreach($data as $key => $value){ and update your code.
Have a nice day !!

Insert into value of Radio button

I am trying to insert the value of a radio button when its checked into mysql db table. Below is the HTML and the PHP for doing so. Please let me know what is going wrong?
Here is the HTML first:
<div class='container'>
<label for='username' >Business*:</label><br/>
<input type="radio" name="bus" id="username" value="bus" maxlength="50" /><br/>
<span id='register_username_errorloc' class='error'></span>
</div>
<div class='container'>
<label for='username' >Personal*:</label><br/>
<input type="radio" name="pers" id="username" value="per" maxlength="50" /><br/>
<span id='register_username_errorloc' class='error'></span>
</div>
Now the PHP:
function InsertIntoDB(&$formvars)
{
$confirmcode = $this->MakeConfirmationMd5($formvars['email']);
$formvars['confirmcode'] = $confirmcode;
$insert_query = 'insert into '.$this->tablename.'(
name,
email,
username,
password,
confirmcode,
dob,
business,
personal
)
values
(
"' . $this->SanitizeForSQL($formvars['name']) . '",
"' . $this->SanitizeForSQL($formvars['email']) . '",
"' . $this->SanitizeForSQL($formvars['username']) . '",
"' . md5($formvars['password']) . '",
"' . $confirmcode . '",
"' . $this->SanitizeForSQL($formvars['dob']) . '",
"' . $this->SanitizeForSQL($formvars['bus']) . '",
"' . $this->SanitizeForSQL($formvars['pers']) . '"
)';
if(!mysql_query( $insert_query ,$this->connection))
{
$this->HandleDBError("Error inserting data to the table\nquery:$insert_query");
return false;
}
return true;
}
I think there is a logical error. You should only save one of the variable in radio button in database.
"' . $this->SanitizeForSQL($formvars['bus']) . '",
"' . $this->SanitizeForSQL($formvars['pers']) . '"

On your code you have this :
$sql.= " where gal_id=" . $gal_id . ";";
$sql.= " username='" . strip_tags(mysql_real_escape_string(trim($username))) . "',";
$sql.= " password='" . strip_tags(mysql_real_escape_string(trim($password))) . "',";
Try to set the where clause after the update of username & password :
$sql.= " username='" . strip_tags(mysql_real_escape_string(trim($username))) . "',";
$sql.= " password='" . strip_tags(mysql_real_escape_string(trim($password))) . "'";
$sql.= " where gal_id=" . $gal_id . ";";
Try this
$sql.= " where gal_id=" . $gal_id . ";";
