Database is not updating with new info

Recommended Posts

I have created a form that i can see the form input info in to the form boxes but once submitted it is not updating or adding new input to the database. I am trying to keep it as simple as possible. I am also new at PHP.

Here is my code:

    <?php
    // define variables and set to empty values
    $amp_20_parts_idErr = $part_numberErr = $locationErr = $quantityErr = "";
    $amp_20_parts_id = $part_number = $discription = $location = $quantity = "";

    if ($_SERVER["REQUEST_METHOD"] == "POST") {
    if (empty($_POST["amp_20_parts_id"])) {
     $amp_20_parts_idErr = "ID is required.";
    } else {
     $amp_20_parts_id= test_input($_POST["amp_20_parts_id"]);
    }
 
    if (empty($_POST["part_number"])) {
     $part_numberErr = "Part number is required.";
    } else {
     $email = test_input($_POST["part_number"]);
    }
  
     if (empty($_POST["description"])) {
     $descriptionErr = "";
    } else {
     $description = test_input($_POST["description"]);
    }
  
    if (empty($_POST["location"])) {
     $locationErr = "A location is required.";
    } else {
     $location = test_input($_POST["location"]);
    }

    if (empty($_POST["quantity"])) {
      $quantityErr = "Quantity is required";
    } else {
      $quantity = test_input($_POST["quantity"]);
    }
    }

    function test_input($data) {
     $data = trim($data);
     $data = stripslashes($data);
     $data = htmlspecialchars($data);
    return $data;
    }
    ?>
  
 <div id="update_form">
  Please follow instructions for updating the data base.<br>instructional text goes here.<br/><br/>
  
    <table><tr><form  method="POST" action="new path">
      <td>ID: <input name="amp_20_parts_id" type="text"><span><?php echo
    $amp_20_parts_idErr; ?></span><br/><br/></td>
      <td>Part Number: <input name="part_number" type="text"><span><?php echo
     $part_numberErr; ?></span><br/><br/></td>
      <td><label>Discription: <textarea name="description" rows="3" col="20"></textarea> 
     <br/><br/></td>
      <td>Location: <input name="location" type="text"><span><?php echo $locationErr;?> 
      </span><br/><br/></td>
      <td>Quantity: <input name="quantity" type="text"><span><?php echo $quantityErr; ?>
      </span><br/><br/></td><br/>
      <td><input type="submit"></td>
      </form></tr></table>
 
 
      <?php
         $con=mysqli_connect("server","user","password","db");

 // Check connection
    if (mysqli_connect_errno()) {
    echo("Connect failed: %s\n", mysqli_connect_error());

 

 // escape variables for security
    $amp_20_parts_id = mysqli_real_escape_string($con, $_POST['amp_20_parts_id']);
    $part_number = mysqli_real_escape_string($con, $_POST['part_number']);
    $discription = mysqli_real_escape_string($con, $_POST['description']);
    $location = mysqli_real_escape_string($con, $_POST['location']);
    $quantity = mysqli_real_escape_string($con, $_POST['quantity']);

     $sql="INSERT INTO amp_20 (amp_20_parts_id, part_number, description, location,
     quantity)
     VALUES ('$amp_20_parts_id', '$part_number', '$description', '$location',
    '$quantity')";

    if (!mysqli_query($con,$sql)) {
      die('Error: ' . mysqli_error($con));
     }
     echo "1 record added";
   
 mysqli_close($con);
    }
    ?>

You seem to be rusty on html as well.  Your input tags have no value= clause.

 

PS - imho - shorter var names are better.  Who needs to be typing 10 or 20 char var names again and again?  Too prone to error.  Plus - as a newbie you would be smart to turn on php error checking - it will come in handy when you do misspell one of the var names.

You have a typo

 

$amp_20_parts_id = $part_number = $discription = $location = $quantity = "";//<- daisy chaining all to blank huh

 

$discription = mysqli_real_escape_string($con, $_POST['description']);

 

$sql="INSERT INTO amp_20 (amp_20_parts_id, part_number, description, location,
     quantity)
     VALUES ('$amp_20_parts_id', '$part_number', '$description', '$location',
    '$quantity')";

I did catch the typo and have corrected it,  I was thinking about shortining the amp_20_ var in the script and the data base, which I have done now as well as shorting the part num var as well, will test and see if it changes the input to where it will add to the data base.

this is the only code i have to input the data to my DB and all the code i pasted is the html inputs and the PHP coding there is nothing more that handles the inputs, but here is just the php script :

<?php
 error_reporting(E_ALL | E_NOTICE);
        ini_set('display_errors', '1');
         $con=mysqli_connect("localhost","scottk","ct@1446SA","part_inventory");
        
    // Check connection
if (mysqli_connect_errno()) {
  printf("Connect failed: %s\n", mysqli_connect_error());


    // escape variables for security
$amp20ptid = mysqli_real_escape_string($con, $_POST['amp20ptid']);
$partnum = mysqli_real_escape_string($con, $_POST['partnum']);
$discription = mysqli_real_escape_string($con, $_POST['description']);
$location = mysqli_real_escape_string($con, $_POST['location']);
$quantity = mysqli_real_escape_string($con, $_POST['quantity']);

$sql = "INSERT INTO amp_20 (amp20ptid, partnum, description, location, quantity)
VALUES ('$amp20ptid', '$partnum', '$description', '$location', '$quantity')";
 
if (!mysqli_query($con,$sql)) {
  die('Error: ' . mysqli_error($con));
}
            
    mysqli_close($con);
}
?>

your form processing code has a misplaced } at the end that's part of the database connection error logic.

 

none of your database INSERT code is running, because it's inside the error handling conditional statement for your database connection. the INSERT code should be inside the form processing logic, where you have tested if the form was submitted and validated the data.

If you gave us the scripts that you actually run we would still be willing to help.  You just can't mislead us.  You have to realize we are trying to help but we are blind here if we can't see your code - good or bad.  Help us to help you by providing the MEANINGFUL code that RELATES to your problem next time.

the thing is we i have giving you the form code as well as the php code and there is nothing more I can give you but what I am running, I just dont know what else to give you, I have the php the pulls from my data base without issue working, I have even taken out the php code out of the main page just to see if that was causing my issues, and i was then starting to see error once that was cleaned up and it was saying "Entered data successfully" it stilll was not updating the database, I will put the php code in was I have now. but this will be what is showing "Entered data successfully". If you need my form code please let me know:

<?php
  $con = mysqli_connect("localhost","user","password","part_inventory");
    // Check connection
if (mysqli_connect_errno()) {
  printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
} else {
    $result = mysqli_query($con, "SELECT * FROM amp20");
    
    // escape variables for security
$amp20ptid = mysqli_real_escape_string($con, $_POST['amp20ptid']);
$partnum = mysqli_real_escape_string($con, $_POST['partnum']);
$location = mysqli_real_escape_string($con, $_POST['location']);
$quantity = mysqli_real_escape_string($con, $_POST['quantity']);

$sql = "INSERT INTO 'part_inventory' . 'amp_20' ('amp20ptid', 'partnum', 'description', 'location', 'quantity')
VALUES('$amp20ptid', '$partnum', $_POST[description], '$location', '$quantity');";

if(! $result)
{
 die('Could not enter data: ' . mysql_error());    
}
 echo "Entered data successfully\n";
    mysqli_close($con);
}
?>

I just got it fixed:

Old code -  die('Could not enter data: ' . mysql_error());   
new code  - die('Could not enter data: ' . mysql_error($con));  

 

then change : old code - $sql = "INSERT INTO 'part_inventory' . 'amp_20' ('amp20ptid', 'partnum', 'description', 'location', 'quantity')

to new code - $sql = "INSERT INTO amp20 (amp20ptid, partnum, description, location, quantity)

i was able to put 2 new entries in to my data base.
