Wordpress $wpdb. Insert Multiple Records - php

Question

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

Answer 1

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 2

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 );

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 {
$query_columns .= "".$key."";
}
}
$values[] = $value;
if(is_numeric($value)) {
if(isset($place_holders[$count])) {
$place_holders[$count] .= ", '%d'";
} else {
$place_holders[$count] .= "( '%d'";
}
} else {
if(isset($place_holders[$count])) {
$place_holders[$count] .= ", '%s'";
} else {
$place_holders[$count] .= "( '%s'";
}
}
}
// mind closing the GAP
$place_holders[$count] .= ")";
}
$query .= " $query_columns ) VALUES ";
$query .= implode(', ', $place_holders);
if($wpdb->query($wpdb->prepare($query, $values))){
return true;
} else {
return false;
}
}

Answer 4

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 #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 5

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 6

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)");
