更新元值对于WordPress中的序列化数据无法正常工作

标签： php wordpress serialization woocommerce metadata

我想知道是否有人可以帮忙解决这个问题。我试图做一个php查询来更新Wordpress上的post meta值。 Pb：字符串必须非常长并且充满非正统字符，如双引号。

结果有点奇怪，因为它得到了更新但是在值周围添加了另一个序列，打破了它，如下所示：

S：5086：＆＃34;的一个：28：{I：0;一个：7：.....

这是最初的查询，如果有人能够弄清楚如何使其符合规定并且令人惊讶：

update_post_meta( $product_id, '_wc_booking_pricing', 'a:28:{i:0;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:5:"0.027";s:13:"base_modifier";s:5:"times";s:4:"from";s:1:"1";s:2:"to";s:1:"3";}i:1;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.02914814815";s:13:"base_modifier";s:5:"times";s:4:"from";s:1:"4";s:2:"to";s:1:"4";}i:2;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:12:"0.0312962963";s:13:"base_modifier";s:5:"times";s:4:"from";s:1:"5";s:2:"to";s:1:"5";}i:3;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.03344444444";s:13:"base_modifier";s:5:"times";s:4:"from";s:1:"6";s:2:"to";s:1:"6";}i:4;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.03559259259";s:13:"base_modifier";s:5:"times";s:4:"from";s:1:"7";s:2:"to";s:1:"7";}i:5;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.03774074074";s:13:"base_modifier";s:5:"times";s:4:"from";s:1:"8";s:2:"to";s:1:"8";}i:6;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.03988888889";s:13:"base_modifier";s:5:"times";s:4:"from";s:1:"9";s:2:"to";s:1:"9";}i:7;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.04203703704";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"10";s:2:"to";s:2:"10";}i:8;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.04418518519";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"11";s:2:"to";s:2:"11";}i:9;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.04633333333";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"12";s:2:"to";s:2:"12";}i:10;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.04848148148";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"13";s:2:"to";s:2:"13";}i:11;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.05062962963";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"14";s:2:"to";s:2:"14";}i:12;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.05277777778";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"15";s:2:"to";s:2:"15";}i:13;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.05492592593";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"16";s:2:"to";s:2:"16";}i:14;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.05707407407";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"17";s:2:"to";s:2:"17";}i:15;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.05922222222";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"18";s:2:"to";s:2:"18";}i:16;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.06137037037";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"19";s:2:"to";s:2:"19";}i:17;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.06351851852";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"20";s:2:"to";s:2:"20";}i:18;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.06566666667";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"21";s:2:"to";s:2:"21";}i:19;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.06781481481";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"22";s:2:"to";s:2:"22";}i:20;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.06996296296";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"23";s:2:"to";s:2:"23";}i:21;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.07211111111";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"24";s:2:"to";s:2:"24";}i:22;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.07425925926";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"25";s:2:"to";s:2:"25";}i:23;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.07640740741";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"26";s:2:"to";s:2:"26";}i:24;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.07855555556";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"27";s:2:"to";s:2:"27";}i:25;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:12:"0.0807037037";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"28";s:2:"to";s:2:"28";}i:26;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.08285185185";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"29";s:2:"to";s:2:"29";}i:27;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cos

2 个答案:

答案 0 :(得分：2)

首先，值得注意的是，您没有进行PHP查询，而是使用WordPress函数（update_post_meta）来保存此数据。这可能就是混乱所在。

您遇到的问题是您传递的是serialized数据。在WordPress中，即使它将数据作为序列化数据存储在数据库中，您也不必自己序列化/反序列化。

WordPress存储“自动”序列化的数据。这意味着当你致电update_post_meta时，你应该简单地传入你想要保存的数组。

这是基于上述代码的 minimal 示例：

$data = array(
    array(
        'type' => 'blocks',
        'cost' => NULL,
        'modifier' => NULL,
        'base_cost' => 0.027,
        'base_modifier] => 'times',
        'from' => 1,
        'to' => 3
    ),
    array(
        'type' => 'blocks',
        'cost' => NULL,
        'modifier' => NULL,
        'base_cost' => 0.02914814815,
        'base_modifier] => 'times',
        'from] => 4,
        'to] => 4
    )
);

update_post_meta( $product_id, '_wc_booking_pricing', $data );

然后，当您使用get_post_meta retreive 数据时，它会将作为数组返回，就像您保存它一样。

答案 1 :(得分：1)

您尝试通过update_post_meta()的字符串是序列化数据，需要先进行反序列化。

两种可能的情况：

1）如果您已对该数据进行序列化，则不要直接在update_post_meta()中传递数据数组。

  

请注意，使用update_post_meta()时，＆＃34;传递的数组将序列化为字符串＆＃34; ，因此在您的情况下，要避免出现一种双重序列化您的数据不可读。

2）如果您自己没有序列化该数据，则可能需要先对此数据进行反序列化。为此，您可以在使用update_post_meta()之前使用WordPress函数maybe_unserialize()，这样：

// Unserializing the data
$data = maybe_unserialize( 'a:28:{i:0;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:5:"0.027";s:13:"base_modifier";s:5:"times";s:4:"from";s:1:"1";s:2:"to";s:1:"3";}i:1;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.02914814815";s:13:"base_modifier";s:5:"times";s:4:"from";s:1:"4";s:2:"to";s:1:"4";}i:2;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:12:"0.0312962963";s:13:"base_modifier";s:5:"times";s:4:"from";s:1:"5";s:2:"to";s:1:"5";}i:3;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.03344444444";s:13:"base_modifier";s:5:"times";s:4:"from";s:1:"6";s:2:"to";s:1:"6";}i:4;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.03559259259";s:13:"base_modifier";s:5:"times";s:4:"from";s:1:"7";s:2:"to";s:1:"7";}i:5;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.03774074074";s:13:"base_modifier";s:5:"times";s:4:"from";s:1:"8";s:2:"to";s:1:"8";}i:6;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.03988888889";s:13:"base_modifier";s:5:"times";s:4:"from";s:1:"9";s:2:"to";s:1:"9";}i:7;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.04203703704";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"10";s:2:"to";s:2:"10";}i:8;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.04418518519";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"11";s:2:"to";s:2:"11";}i:9;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.04633333333";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"12";s:2:"to";s:2:"12";}i:10;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.04848148148";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"13";s:2:"to";s:2:"13";}i:11;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.05062962963";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"14";s:2:"to";s:2:"14";}i:12;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.05277777778";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"15";s:2:"to";s:2:"15";}i:13;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.05492592593";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"16";s:2:"to";s:2:"16";}i:14;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.05707407407";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"17";s:2:"to";s:2:"17";}i:15;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.05922222222";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"18";s:2:"to";s:2:"18";}i:16;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.06137037037";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"19";s:2:"to";s:2:"19";}i:17;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.06351851852";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"20";s:2:"to";s:2:"20";}i:18;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.06566666667";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"21";s:2:"to";s:2:"21";}i:19;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.06781481481";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"22";s:2:"to";s:2:"22";}i:20;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.06996296296";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"23";s:2:"to";s:2:"23";}i:21;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.07211111111";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"24";s:2:"to";s:2:"24";}i:22;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.07425925926";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"25";s:2:"to";s:2:"25";}i:23;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.07640740741";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"26";s:2:"to";s:2:"26";}i:24;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.07855555556";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"27";s:2:"to";s:2:"27";}i:25;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:12:"0.0807037037";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"28";s:2:"to";s:2:"28";}i:26;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cost";s:13:"0.08285185185";s:13:"base_modifier";s:5:"times";s:4:"from";s:2:"29";s:2:"to";s:2:"29";}i:27;a:7:{s:4:"type";s:6:"blocks";s:4:"cost";s:0:"";s:8:"modifier";s:0:"";s:9:"base_cos
