I want to retrieve data from my database for editing by user and I don't know where I'm going wrong...
The codes below are supposed to return the information from the database in json format and insert them into existing textboxes for user edit...
My problem is that, when the update button is clicked, nothing works... there is no response from the browser...
Please help... I'm new to all of this
Code to retrieve data from database (fetch.php):
<?php
$connect= mysqli_connect("localhost", "Eben", "Pass1234", "stageupgh");
if (isset($_POST['item_id'])) {
$output= array();
$procedure= "
CREATE PROCEDURE whereItem(IN item_id int(11))
BEGIN
SELECT * FROM items WHERE item_id= item_id;
END;
";
if (mysqli_query($connect, "DROP PROCEDURE IF EXISTS whereItem")) {
if (mysqli_query($connect, $procedure)) {
$query= "CALL whereItem(".$_POST['item_id'].")";
$result= mysqli_query($connect, $query);
while ($row= mysqli_fetch_array($result)) {
$output["itemName"]= $row["name"];
$output['itemDescription']= $row["description"];
$output['stock']= $row["in_stock"];
$output['price']= $row["price"];
}
echo json_encode($output);
}
}
}
?>
itemAction.php:
<?php
if (isset($_POST["action"])) {
$output= '';
$connect= mysqli_connect("localhost", "Eben", "Pass1234", "stageupgh");
if ($_POST["action"]=="Add") {
$itemName= mysqli_real_escape_string($connect, $_POST["itemName"]);
$itemDescription= mysqli_real_escape_string($connect, $_POST["itemDescription"]);
$stock= mysqli_real_escape_string($connect, $_POST["stock"]);
$price= mysqli_real_escape_string($connect, $_POST["price"]);
$procedure= "
CREATE PROCEDURE insertItem(IN name varchar(100), description varchar(250), in_stock int(11), price decimal(6,2))
BEGIN
INSERT INTO items(name, description, in_stock, price) VALUES (name, description, in_stock, price);
END
";
if (mysqli_query($connect, "DROP PROCEDURE IF EXISTS insertItem")) {
if(mysqli_query($connect, $procedure)){
$query= "CALL insertItem('".$itemName."', '".$itemDescription."','".$stock."','".$price."')";
mysqli_query($connect, $query);
echo "Data Inserted";
}
}
}
if (isset($_POST['action'])=="Edit") {
$itemName= mysqli_real_escape_string($connect, $_POST["itemName"]);
$itemDescription= mysqli_real_escape_string($connect, $_POST["itemDescription"]);
$stock= mysqli_real_escape_string($connect, $_POST["stock"]);
$price= mysqli_real_escape_string($connect, $_POST["price"]);
$procedure= "
CREATE PROCEDURE updateItem(IN item_id int(11), name varchar(100), description varchar(250), in_stock int(11), price decimal(6,2))
BEGIN
UPDATE items SET name= itemName, description= itemDescription, in_stock= stock, price= price WHERE item_id= item_id;
END;
";
if (mysqli_query($connect, "DROP PROCEDURE IF EXISTS updateUser")) {
if (mysqli_query($connect, $procedure)) {
$query= "CALL updateUser('".$_POST['item_id']."', '".$itemName."', '".$itemDescription."',, '".$stock."', '".$price."')";
mysqli_query($connect, $query);
echo "Data Updated";
}
}
}
}
?>
