显示数据库内部的数据 <table> 使用wordpress $ wpdb

Question

Can someone help me, how to code the logic to print the data from my database into a <table> ?

<table border="1">
    <tr>
     <th>Firstname</th>
     <th>Lastname</th>
     <th>Points</th>
    </tr>
    <tr>
      <?php
        global $wpdb;
        $result = $wpdb->get_results ( "SELECT * FROM myTable" );
        foreach ( $result as $print )   {
            echo '<td>' $print->firstname.'</td>';
            }
      ?>
    </tr>               
</table>

i know this is so basic, but im really having a hard time to make this work.

Try this:

<table border="1">
<tr>
 <th>Firstname</th>
 <th>Lastname</th>
 <th>Points</th>
</tr>
  <?php
    global $wpdb;
    $result = $wpdb->get_results ( "SELECT * FROM myTable" );
    foreach ( $result as $print )   {
    ?>
    <tr>
    <td><?php echo $print->firstname;?></td>
    </tr>
        <?php }
  ?>

You just need to put <tr> inside your foreach loop ,and add . concatenation operator in your line ,you nee alsotry this :

• You need to wrap <td></td> inside <tr></tr> in foreach loop
• You need to add . concatenation operator in line that contains firstname variable.

• If you have duplicate values , then add this parameter ARRAY_A to your query

  $result = $wpdb->get_results ( "SELECT * FROM myTable",ARRAY_A ); .

   <table border="1"> <tr> <th>Firstname</th> <th>Lastname</th> <th>Points</th> </tr> <?php global $wpdb; $result = $wpdb->get_results ( "SELECT * FROM myTable" ); foreach ( $result as $print ) { echo '<tr>'; echo '<td>' . $print->firstname .'</td>'; echo '<td>' . $print->lastname .'</td>'; echo '<td>' . $print->points .'</td>'; echo '</tr>'; } ?> </table> 

Answer 3

You're missing . in echo '<td>' $print->firstname.'</td>';

Try this

<?php
  global $wpdb;
  $result = $wpdb->get_results ( "SELECT * FROM myTable" );
    foreach ( $result as $print )   {

      echo '<tr>';
      echo '<td>' . $print->firstname.'</td>';
      echo '<td>' . $print->lastname.'</td>';
      echo '<td>' . $print->points.'</td>';
      echo '</tr>';
  }
?>

Try this:

$result = $wpdb->get_results("SELECT * FROM myTable" , ARRAY_A); //get result as associative array

Then the usual cycle:

//spare memory
$count = count($result);
//fastest way to perform the cycle
for ($i = $count; $i--;) {
   echo '<td>'. $print[$i]['firstname'].'</td>';
}
