I am trying to create custom input tables to send data into custom tables on the wp database. I cannot get my script to do anything. The user will enter a type of liquor, like vodka or whiskey, provide a description, and send it to the database, where there are custom tables within the wordpress database. I have the html code in a wordpress page and the php in a file called setLiquorType.php that is in the main wordpress folder.


<form method = "post" action = "setLiquorType.php">
Add a New Liquor Type</br></br>
<p>Name: <input type="text" name="name"/></p>
<p>Description <input type="text" name="description"/></p>
<input type="submit" value="Submit"/>

My php script

$name = $_POST['name'];
$global $wpdb, $name, $description;
$table_name = $wpdb->prefix . "Liquor Type";
$wpdb->insert($table_name, array(
                            'lq_name' => $lq_name,
                            'description' => $lq_descrip

Any help would be great

    Does your data match the data types you are providing? Do you have debugging enabled? – s_ha_dum Oct 14 '14 at 21:32
  • Just noticed you're using $global $wpdb instead of global $wpdb, so I'm guessing your insert code isn't running. – TomC Apr 26 '16 at 10:30
  • Another problem could be that your table name contains a space, so the SQL couldn't be parsed properly. – Nimrod Oct 27 '16 at 19:51

You said your form is in the main folder? I guess you need to set proper URL for action="". You could try:

action="<?php echo site_url() . '/setLiquorType.php'; ?>"

It is best practice to put your form code into functions.php and then leave form action="" empty. Then you can trigger your form function when form is submitted.

Your Form HTML:

<form method = "post" action = ""> //edited form action

      <h3>Add a New Liquor Type</h3> //wrapped title with <h3> tags and removed <br> because h3 element will have padding that will separate it from form (if not provided in your style.css it will be assigned by the browser)
      <p>  //wraping field with paragraph to generate automatic space between them without styling it
         <label for="name">Name:</label>  //removed <p> element and used <label> instead
         <input type="text" name="name"/>
         <label for="description">Description</label>
         <input type="text" name="description"/>
      <hr> //replaced unnecessary --- lines 
      <input type="submit" value="Submit" name="liquor_submit"/>  // added name attribute that will be used to check if the form is submitted

Now in you functions.php you can add something like:

    //setting up the form
    function themename_add_new_liquor() {

      $name         = $_POST['name'];
      $description  = $_POST['description'];  //You forgot to collect data from "description" field

      global $wpdb; //removed $name and $description there is no need to assign them to a global variable
      $table_name = $wpdb->prefix . "liquor_type"; //try not using Uppercase letters or blank spaces when naming db tables

      $wpdb->insert($table_name, array(
                                'lq_name' => $name, //replaced non-existing variables $lq_name, and $lq_descrip, with the ones we set to collect the data - $name and $description
                                'description' => $description
                                '%s') //replaced %d with %s - I guess that your description field will hold strings not decimals

//And now to connect the  two:  
if( isset($_POST['liquor_submit']) ) themename_add_new_liquor();

I hope this can help. Also, non of this will work if you have not created your Database table in the first place ( $wpdb->insert function is used for inserting data in the existing table ).

Cheers! :)
