Wordpress $wpdb。插入多条记录
Wordpress $wpdb。插入多条记录
提问于 2012-09-12 00:13:11
有没有办法在Wordpress中用$wpdb->insert或
$wpdb->query($wpdb->prepare))
INSERT into TABLE (column1, column2, column3)
VALUES
('value1', 'value2', 'value3'),
('otherval1', 'otherval2', 'otherval3'),
('anotherval1', 'anotherval2', 'anotherval3')...etc

好了，我想通了！
设置实际值和占位符的数组
$values = array();
$place_holders = array();初始查询：
$query = "INSERT INTO orders (order_id, product_id, quantity) VALUES ";然后循环遍历要添加的值，并将它们插入到适当的数组中：
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 */
}然后将这些位添加到初始查询中：
$query .= implode( ', ', $place_holders );
$wpdb->query( $wpdb->prepare( "$query ", $values ) );Stack Overflow用户

您还可以使用此方法构建查询：
$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 );Stack Overflow用户

我遇到了这个问题，并决定使用accepted构建一个更好的函数：
/**
* 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;
