No input file specified when sending email php - php

Question

UPDATE: non of any php files is running. Is there a way to solve the problem ?
I have html a page that takes the email details:
<form method="POST" sourceindex="44" action="semail.php" name="form1" onSubmit="return validate_form ( );">
<p>
<label>Your name:<br>
<input sourceindex="47" name="mail_name" class="text_field" type="text">
</label>
</p>
<p>
<label>Your e-mail:<br>
<input sourceindex="51" name="mail_email"
class="text_field" type="text">
</label>
</p>
<p>
<label>Message:<br>
<textarea sourceindex="55" name="mail_msg" cols="45"
rows="5" class="text_area"></textarea>
</label>
</p>
<input name="B1" type="submit" class="form_button" value="" />
</form>
and here is the php code (this is all in semail.php):
<?php
$mail_to ="someEmail#hotmail.com";
$mail_subject = "Message From a Customer";
$mail_body ="Name of the Coustomer: ".$_POST['mail_name']."\n";
$mail_body .= "E-Mail Of the Coustomer: ".$_POST['mail_email']."\n";
$mail_body .= "The Message: ".$_POST['mail_msg']."\n";
if(mail($mail_to, $mail_subject, $mail_body))
echo "Thanks for your Message";
else
echo "Failed to send the e-mail"
?>
Whenever I click send the semail.php page shows me this error: No input file specified
Can someone help me please in figuring out where is the problem ?

Answer 1

To first check and verify that PHP is running and available with the present Web hosting company, create a file called check_server.php and insert the following code:
<?php
// Show all information, defaults to INFO_ALL
phpinfo();
// Show just the module information.
// phpinfo(8) yields identical results.
phpinfo(INFO_MODULES);
?>
If successful, you will see your server information and configurations. It will also show the path to mail.
Regarding your form code:
My answer may or may not solve a probable Hosting company issue, however there were a few errors in your code which would result as unsuccessful.
Please read the following:
In using the following form, had success in sending and receiving the message.
<form method="POST" sourceindex="44" action="semail.php" name="form1">
<p>
<label>Your name:<br>
<input sourceindex="47" name="mail_name" class="text_field" type="text">
</label>
</p>
<p>
<label>Your e-mail:<br>
<input sourceindex="51" name="mail_email"
class="text_field" type="text">
</label>
</p>
<p>
<label>Message:<br>
<textarea sourceindex="55" name="mail_msg" cols="45"
rows="5" class="text_area"></textarea>
</label>
</p>
<input name="B1" type="submit" class="form_button" value="Submit" />
</form>
N.B.: I do need to point out that your PHP mail handler did not contain a few required elements.
For example the From: element/variable which was not present in your handler.
$mail_email= $_POST['mail_email'];
Also headers were not present. Mail requires 4 variables to send/receive Email.
For example you have if(mail($mail_to, $mail_subject, $mail_body))
Which should read as if(mail($mail_to, $mail_subject, $mail_body, $headers))
Omitting the headers would result in a message marked as SPAM because of the missing Email from and would show as unknown sender
In conjunction with the form above, am including a working copy of the PHP mail handler:
<?php
$mail_to ="someEmail#hotmail.com";
$mail_email= $_POST['mail_email'];
$mail_subject = "Message From a Customer";
$mail_body ="Name of the Customer: ".$_POST['mail_name']."\n";
$mail_body .= "E-Mail Of the Coustomer: ".$_POST['mail_email']."\n";
$mail_body .= "The Message: ".$_POST['mail_msg']."\n";
$headers = "From: $mail_email \r\n";
$headers .= "Reply-To: $mail_email \r\n";
if(mail($mail_to, $mail_subject, $mail_body, $headers))
echo "Thanks for your Message";
else
echo "Failed to send the e-mail";
?>
