两种形式相互冲突

Question

I have placed two forms on one page. Bothe forms work fine separately but when they are placed on one page at the same time they conflict with each other. Here are both forms:

Contact Form:

<form name="contactform" id="contactform" method="post" action="#targetAnchorPage2">
<table>
<?php
if (isset($_POST["name"])){
?>
<tr>
 <td colspan="2" class="error">
 <?php
 require_once("contact_send.php");
 ?>
 </td>
</tr>
<?php
}
?>

<tr><td><label for="name" class="<?=$name_class?>">name:</label></td><td><input  type="text" name="name" maxlength="50" value="<?=$name?>"></td></tr>
<tr><td><label for="email" class="<?=$emailaddress_class?>">email:</label></td><td><input  type="text" name="email" maxlength="80" value="<?=$emailaddress?>"></td></tr>
<tr><td colspan="2"><label id="tworows" for="message" class="<?=$message_class?>">your message:</label></td></tr><tr><td colspan="2"><textarea  name="message" cols="22" rows="6" value="<?=$message_class?>"></textarea>
 </td></tr>

<tr>
 <td colspan="2" style="text-align:center"><br /><input class="button" type="submit" value="">   
 </td>
</tr>

</table>
</form>

Subscribe Form:

<form name="subscribeform" id="subscribeform" method="post" action="#targetAnchorPage3">
<table>
<?php
if (isset($_POST["name"])){
?>
<tr>
 <td colspan="2" class="error">
 <?php
 require_once("subscribe_send.php");
 ?>
 </td>
</tr>
<?php
}
?>

<tr><td><label for="name" class="<?=$name_class?>">name:</label></td><td><input type="text" name="name" maxlength="50" value="<?=$name?>"></td></tr>
<tr><td><label for="email" class="<?=$emailaddress_class?>">email:</label></td><td><input type="text" name="email" maxlength="80" value="<?=$emailaddress?>"></td></tr>

<tr>
 <td colspan="2" style="text-align:center"><br /><input class="button" type="submit" value="">   
 </td>
</tr>

</table>
</form>

How can this be solved? Is it caused by the "required_once" command?

Answer 1

I am guessing that since you are showing the required files based on the same criteria isset($_POST['name']) and since both forms have the name field you end up showing the code in both requires regardless of which form is submitted. You should simply change the form field names on on of the forms such that they are different.
