Question

我正在尝试将数据插入使用$ wpdb创建的sql表中

我尝试了很多事情，但是没有一件对我有用。有任何想法吗？（我有一个具有自动递增功能的id列）

<?php /* Template Name: My Custom Page */ 
require_once("header.php");
                    ?>    
<div class="wrap">

      <form action="" method="post">
          FFFirstName <input type="text" name="nametxt" value="" /><br/>

          <input name="Submit" type="submit" value="Submit">
      </form>
          <?php   
          if( isset($_POST['submit']) )
              {
                global $wpdb;  
                  $firstName = $_POST["nametxt"];
                    echo $firstName;
         $table = $wpdb->prefix."invoice";  
        $wpdb->insert($table,array('name' => $firstName ));
        }

 $wpdb->print_error(); 
  $wpdb->show_errors();     
     ?>   
     </div>

Answer 1

尝试一下

ALTER TABLE wp_invoice修改列ID INT（5）自动递增

<?php 
/* 
Template Name: My Custom Page
*/ 


      if( isset($_POST['submit']) )
          {
            global $wpdb;  
            $firstName = $_POST["nametxt"];
            echo $firstName;
            $table = $wpdb->prefix."invoice";  
            $wpdb->insert($table,array('name' => $firstName ));
       }

    $wpdb->print_error(); 
    $wpdb->show_errors();     
   ?> 
  <?php require_once("header.php");?>
<div class="wrap">

      <form action="" method="post">
      FFFirstName <input type="text" name="nametxt" value="" /><br/>

      <input name="submit" type="submit" value="Submit">
      </form>

</div>

表结构

table `wp_invoice`
--

CREATE TABLE `wp_invoice` (
  `ID` int(5) NOT NULL,
  `name` varchar(20) NOT NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1;

--
-- Dumping data for table `wp_invoice`
--

INSERT INTO `wp_invoice` (`ID`, `name`) VALUES
(2, 'shasy'),
(0, 'shay');

--
-- Indexes for dumped tables
--

--
-- Indexes for table `wp_invoice`
--
ALTER TABLE `wp_invoice`
  ADD PRIMARY KEY (`ID`) USING BTREE;
COMMIT;
