Question

我有一个php文件，我希望用户从两个下拉列表中选择值，并在提交一些代码后执行。在测试之后我注意到，它读取了第一个echo，它通知用户已经选择了这两个特定值，但是所有其他代码（应该显示这两个值的连接）都不会执行。我觉得我很安全，但我觉得我需要一些推动力。以下是代码

<form method="GET" action="">
    <table>
    <tr><br /><br /><center><h2>Επιλέξτε τις ομάδες για τις οποίες θέλετε να δείτε το ιστορικό</h2><center><br /></tr>
    <tr>
    <td><i>Επιλογή 1ης ομάδας</i></td>
    <td>
        <select id="Team1" name="Team1"><option value="0">Καμία επιλογή</option>
        <?php
global $wpdb;
$table = $wpdb->prefix . 'leagueengine_data';
$table2 = $wpdb->prefix . 'leagueengine_tournament_matches';
$teams = $wpdb->get_results("SELECT * FROM $table WHERE data_type = 'team' ORDER BY data_value ASC");
foreach ( $teams as $teams ) 
{   $team_id = $teams->id;
$team_name = $teams->data_value;
echo '<option value="'.$team_id.'">'.leagueengine_fetch_data_from_id($teams->id,'data_value') .'</option>';
}
$output .= '</div>';
?>  
</select>
</td></tr>

Answer 1

真的很抱歉没用，因为它似乎发布了。用echo：/

替换输出后，一切都解决了

即使它读取变量，PHP也不会执行
