Question

我想实现联系表单，但浏览器将php代码显示为纯文本。这是代码：

<div id="main-container">

    <div id="form-container">
    <h1>Fancy Contact Form</h1>
    <h2>Drop us a line and we will get back to you</h2>

    <form id="contact-form" name="contact-form" method="post" action="submit.php">
      <table width="100%" border="0" cellspacing="0" cellpadding="5">
        <tr>
          <td width="15%"><label for="name">Name</label></td>
          <td width="70%"><input type="text" class="validate[required,custom[onlyLetter]]" name="name" id="name" value="<?=$_SESSION['post']['name']?>" /></td>
          <td width="15%" id="errOffset">&nbsp;</td>
        </tr>
        <tr>
          <td><label for="email">Email</label></td>
          <td><input type="text" class="validate[required,custom[email]]" name="email" id="email" value="<?=$_SESSION['post']['email']?>" /></td>
          <td>&nbsp;</td>
        </tr>
        <tr>
          <td><label for="subject">Subject</label></td>
          <td><select name="subject" id="subject">
            <option value="" selected="selected"> - Choose -</option>
            <option value="Question">Question</option>
            <option value="Business proposal">Business proposal</option>
            <option value="Advertisement">Advertising</option>
            <option value="Complaint">Complaint</option>
          </select>          </td>
          <td>&nbsp;</td>
        </tr>
        <tr>
          <td valign="top"><label for="message">Message</label></td>
          <td><textarea name="message" id="message" class="validate[required]" cols="35" rows="5"><?=$_SESSION['post']['message']?></textarea></td>
          <td valign="top">&nbsp;</td>
        </tr>
        <tr>
          <td><label for="captcha"><?=$_SESSION['n1']?> + <?=$_SESSION['n2']?> =</label></td>
          <td><input type="text" class="validate[required,custom[onlyNumber]]" name="captcha" id="captcha" /></td>
          <td valign="top">&nbsp;</td>
        </tr>
        <tr>
          <td valign="top">&nbsp;</td>
          <td colspan="2"><input type="submit" name="button" id="button" value="Submit" />
          <input type="reset" name="button2" id="button2" value="Reset" />

          <?=$str?>          <img id="loading" src="img/ajax-load.gif" width="16" height="16" alt="loading" /></td>
        </tr>
      </table>
      </form>
      <?=$success?>
    </div>
    <div class="tutorial-info"> 
    This is a Tutorialzine demo. View the <a href="http://tutorialzine.com/2009/09/fancy-contact-form/">original tutorial</a>, or download the <a href="demo.zip">demo files</a>.    </div>

</div>

所以，我得到了这些

<?=$_SESSION['post']['name']?>
<?=$_SESSION['post']['email']?>
<?=$_SESSION['post']['message']?>

在表单字段中显示为纯文本。怎么了？请帮助。

Answer 1

您是否支持在php.ini配置中启用short tags？可能就是这样。

Answer 2

在PHP 5.4.0之前，速记语句受short_open_tag配置的影响。你可能想检查一下。请注意，建议不要使用这些简写语句，只是回显您的值。它产生更强大和可移植的代码。

Answer 3

在某些服务器中，您无法使用<?=，因此您必须使用此功能：

<?php echo $_SESSION['post']['name']; ?>

或者只是在php.ini中启用短标签

Answer 4

PHP.ini中可能禁用了短标签，你不应该使用它们

更改<?= 到

<?php echo

Answer 5

试试这个

 value="<?php echo $_SESSION['post']['name']; ?>"

和第二

value="<?php echo $_SESSION['post']['email'] ; ?>"

和第三

 <?php echo $_SESSION['post']['message'] ; ?>

等等
