我正在为 wordpress 制作服装元盒。麻烦的是wordpress似乎只保留/保存我在字段中输入的一些值..我也找不到模式..所以这里是代码:
<?php
function add_products_metaboxes() {
add_meta_box('sra_product_info', 'Product Information', 'sra_products_info', 'product', 'side', 'default');
}
// The Productinfo Metabox
function sra_products_info() {
//get access to the post object
global $post;
// Noncename needed to verify where the data originated
echo '<input type="hidden" name="productmeta_noncename" id="productmeta_noncename" value="' .
wp_create_nonce( plugin_basename(__FILE__) ) . '" />';
// Get the data from the field if its already been entered
$name = get_post_meta($post->ID, '_name', true);
$price = get_post_meta($post->ID, '_price', true);
$includes = get_post_meta($post->ID, '_includes', true);
$supports = get_post_meta($post->ID, '_supports', true);
$version = get_post_meta($post->ID, '_version' , true);
$extrainfo = get_post_meta($post->ID, '_extrainfo', true);
// Echo out the form
echo '<form>';
echo '<label for="_name">Name</label>' . '<input type="text" name="_name" value="' . $name . '"/>';
echo '<label for="_price">Price</label>' . '<input type="text" name="_price" value="' . $price . '"/>';
echo '<label for="_includes">Includes</label> <textarea name="_includes" rows="4" cols="10">' . $includes . '</textarea>';
echo '<label for="_supports">Supports</label> <input type="text" name="_supports" value="' . $supports . '"/>';
echo '<label for="_version">Version</label>' . '<input type="text" name="_version" value="' . $version . '"/>';
echo '<label for="_extrainfo">Extras</label> <textarea name="_extrainfo" rows="4" cols="10">' . $extrainfo . '</textarea>';
echo '</form>';
}
// Save the Metabox Data
function sra_save_product_meta($post_id, $post) {
// verify this came from the our screen and with proper authorization,
// because save_post can be triggered at other times
if ( !wp_verify_nonce( $_POST['productmeta_noncename'], plugin_basename(__FILE__) )) {
return $post->ID;
}
// Is the user allowed to edit the post or page?
if ( !current_user_can( 'edit_post', $post->ID ))
return $post->ID;
// OK, we're authenticated: we need to find and save the data
// check if the field exists in the posts array - if it does, then put cintent in $product_meta.
// this code needs to be refactored!
if (isset($_POST['_name'])) {
$product_meta['_name'] = $_POST['_name'];
}
if (isset($_POST['_price'])) {
$product_meta['_price'] = $_POST['_price'];
}
if (isset($_POST['_includes'])) {
$product_meta['_includes'] = $_POST['_includes'];
}
if (isset($_POST['_supports'])) {
$product_meta['_supports'] = $_POST['_supports'];
}
if (isset($_POST['_version'])) {
$product_meta['_version'] = $_POST['_version'];
}
if (isset($_POST['_extrainfo'])) {
$product_meta['_extrainfo'] = $_POST['_extrainfo'];
}
// Add values of $prpduct_meta as custom fields
foreach ($product_meta as $key => $value) { // Cycle through the $product_meta array!
if( $post->post_type == 'revision' ) return; // Don't store custom data twice
$value = implode(',', (array)$value); // If $value is an array, make it a CSL (unlikely)
if(get_post_meta($post->ID, $key, FALSE)) { // If the custom field already has a value
update_post_meta($post->ID, $key, $value);
} else { // If the custom field doesn't have a value
add_post_meta($post->ID, $key, $value);
}
if(!$value) delete_post_meta($post->ID, $key); // Delete if blank
}
}
add_action('save_post', 'sra_save_product_meta', 1, 2); // save the custom fields
你看到任何明显的错误吗?我想我对这段代码中自己的错误有点盲目。
