PHP Not getting text from textbox

问题:

Whenever I enter text into the textbox, it is not properly transferring to PHP. PHP reads the input as null, when in reality, there is text in there.

PHP code.

    //Two Email Lines
$email_to = "[e-mail]";
$email_subject = "AUTO: REQUEST";

//Set equal to email form textbox
$email_form = $_POST['email_text'];


$email_message = "Email: " . $email_form . "";

//Create email headers
@mail($email_to, $email_subject,$email_message,$headers);

HTML code for the form

<div id="form">

<form method="post" action="Email_Form_Script.php" enctype="text/plain" onsubmit="window.open('FormPopUp.html','popup','width=500,height=500,scrollbars=no,resizable=no,toolbar=no,directories=no,location=no,menubar=no,status=no,left=0,top=0');" >
    <div>
        <input type="text" class="text" name="e3text" id="emailForm" value="Enter your e-mail address" onfocus="if(this.value=='Enter your e-mail address') { this.value = '' }" onblur="if(this.value=='') { this.value = 'Enter your e-mail address' }" />
        <input type="hidden" value="" name="email2"/>
        <input type="hidden" name="loc" value="en_US"/>
        <input type="submit" class="submit" value=""/></div>
</form>
</div>

Really confused as to why it is not working. I keep getting empty emails that just say " Email: " (No text after Email).

Its because your form doesn't actually contain an input element named email_text which is referenced in your PHP code. You need to structure your HTML form code to at least look like this or change your PHP code to require $_POST['e3text'].

<div id="form">
    <form method="post" action="Email_Form_Script.php" enctype="text/plain" onsubmit="window.open('FormPopUp.html','popup','width=500,height=500,scrollbars=no,resizable=no,toolbar=no,directories=no,location=no,menubar=no,status=no,left=0,top=0');" >
        <div>
            <input type="text" class="text" name="email_text" id="emailForm" value="Enter your e-mail address" onfocus="if(this.value=='Enter your e-mail address') { this.value = '' }" onblur="if(this.value=='') { this.value = 'Enter your e-mail address' }" />
            <input type="hidden" value="" name="email2"/>
            <input type="hidden" name="loc" value="en_US"/><input type="submit" class="submit" value="" />
        </div>
    </form>
</div>

The line:

$email_form = $_POST['email_text'];

needs to match the name of the text in the form which in your case is name="e3text" so you should use:

$email_form = $_POST['e3text'];

回答3:

try this in your php code

$email_form = $_POST['e3text'];

"e3text" is the name of your text box so in php use this name

回答4:

When you hit the submit button of your form, values are passed as:

name of the input field = value of the input field

Your field is name e3text - please refer to such field in your script, i.e. $_POST['e3text'].
