save values from editable table using php

Question

Hi I have a table generated from php, it is editable, I want to save edited values to database. I have no Idea how can I do this as there are many rows(dynamic) on a page. Here

Answer 1

Let me give you with the best way First your database tables have spaces: correct that e.g.

from $row["Initial Stock"] to $row["Initial_Stock"]

Then i will propose you use ajax instead of wasting time clicking buttons

The HTML Page

 




 
 
 






";



    fetch_assoc()) ?>
 




  

    
Sl Number
    
Product Id
    
Product Name
    
Product Catagory
    
Retal Price
    
Max Price
    
Min Price
    
Initial Stock
    
Quantity Sold
    
Current Stock
    
Last Order
    
Edit/Update

">
    
">
    
">
    
">

And the update php page

    false,
                  PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION));


?>

 $val)
    {
        //clean post values
        $field_id = strip_tags(trim($field_name));

        //from the fieldname:user_id we need to get user_id
        $split_data = explode(':', $field_id);
        $product_id = $split_data[1];
        $field_name = $split_data[0];
        if(!empty($product_id) && !empty($field_name) && !empty($val))
        {

            $affected_rows = $db->exec("UPDATE yourtable SET $field_name = '$val' WHERE product_ID = $product_id");
            echo $affected_rows;

            echo "Updated";
        } else {
            echo "Invalid Requests";
        }
    }
} 

else {
    echo "Invalid Requests";
}
?>
