php – WordPress $wpdb. Insert Multiple Records

Posted by: admin April 23, 2020 Leave a comment

Questions:

Is there any way to accomplish the following in WordPress with $wpdb->insert or

$wpdb->query($wpdb->prepare)):

INSERT into TABLE (column1, column2, column3) 
VALUES
('value1', 'value2', 'value3'),
('otherval1', 'otherval2', 'otherval3'),
('anotherval1', 'anotherval2', 'anotherval3')

…etc

How to&Answers:

OK, I figured it out!

Setup arrays for Actual Values, and Placeholders

$values = array();
$place_holders = array();

the initial Query:

$query = "INSERT INTO orders (order_id, product_id, quantity) VALUES ";

Then loop through the the values you’re looking to add, and insert them in the appropriate arrays:

foreach($_POST as $key => $value)
{
     array_push($values, $value, $order_id);
     $place_holders[] = "('%d', '%d')" /* In my case, i know they will always be integers */
}

Then add these bits to the initial query:

$query .= implode(', ', $place_holders);
$wpdb->query( $wpdb->prepare("$query ", $values));

Answer:

You can also use this way to build the query:

$values = array();

// We're preparing each DB item on it's own. Makes the code cleaner.
foreach ( $items as $key => $value ) {
    $values[] = $wpdb->prepare( "(%d,%d)", $key, $value );
}

$query = "INSERT INTO orders (order_id, product_id, quantity) VALUES ";
$query .= implode( ",\n", $values );

Answer:

I have came across with this problem and decided to build a more improved function by using accepted answer too:

/**
 * A method for inserting multiple rows into the specified table
 * 
 *  Usage Example: 
 *
 *  $insert_arrays = array();
 *  foreach($assets as $asset) {
 *
 *  $insert_arrays[] = array(
 *  'type' => "multiple_row_insert",
 *  'status' => 1,
 *  'name'=>$asset,
 *  'added_date' => current_time( 'mysql' ),
 *  'last_update' => current_time( 'mysql' ));
 *
 *  }
 *
 *  wp_insert_rows($insert_arrays);
 *
 *
 * @param array $row_arrays
 * @param string $wp_table_name
 * @return false|int

function wp_insert_rows($row_arrays = array(), $wp_table_name) {
    global $wpdb;
    $wp_table_name = esc_sql($wp_table_name);
    // Setup arrays for Actual Values, and Placeholders
    $values = array();
    $place_holders = array();
    $query = "";
    $query_columns = "";

    $query .= "INSERT INTO {$wp_table_name} (";

            foreach($row_arrays as $count => $row_array)
            {

                foreach($row_array as $key => $value) {

                    if($count == 0) {
                        if($query_columns) {
                        $query_columns .= ",".$key."";
                        } else {

                        }
                    } else {
                        if(isset($place_holders[$count])) {
                        $place_holders[$count] .= ", '%s'";
                        } else {
                        $place_holders[$count] .= "( '%s'";

    $query .= " $query_columns ) VALUES ";

    $query .= implode(', ', $place_holders);

    if($wpdb->query($wpdb->prepare($query, $values))){
        return true;
    } else {
        return false;
    }

Answer:

In addition to inserting multiple rows using $wpdb, if you ever need to update existing rows following snippet should be helpful.
This is updated snippet of what my friend @philipp provided above.

$values = array();

// We're preparing each DB item on it's own. Makes the code cleaner.
foreach ( $items as $key => $value ) {
    $values[] = $wpdb->prepare( "(%d,%d)", $key, $value );
}

$values = implode( ",\n", $values );
$query = "INSERT INTO orders (order_id, product_id, quantity) VALUES {$values} ON DUPLICATE KEY UPDATE `quantity` = VALUES(quantity)";

Answer:

This is a bit late, but you could also do it like this.

    global $wpdb;
    $table_name = $wpdb->prefix . 'your_table';

    foreach ($your_array as $key => $value) {
          $result = $wpdb->insert( 
            $table_name, 
            array( 
              'colname_1' => $value[0], 
              'colname_2' => $value[1], 
              'colname_3' => $value[2], 
            ) 
          );
        }
  if (!$result) {
    print 'There was a error';
  }

Answer:

not very nice, but if you know what you are doing:

require_once('wp-load.php');
mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);  
@mysql_select_db(DB_NAME) or die();
mysql_query("INSERT into TABLE ('column1', 'column2', 'column3') VALUES 
                               ('value1', 'value2', 'value3'), 
                               ('otherval1', 'otherval2', 'otherval3'),
                               ('anotherval1', 'anotherval2', 'anotherval3)");
