PHP mailform code

[chechu]

Sometimes I receive the mails, sometimes I don't.
Is this code correct ?


<?
if ($_POST["Submit"]){

if ($_POST["name"] and $_POST["email"] and $_POST["subject"] and $_POST["message"] ){



//mail gegevens

mail (
"info@casariegoart.com",
"via website (EN)",
"
Name: ".$_POST['name']."
E-mail: ".$_POST['email']."
Subject: ".$_POST['subject']."
Message: ".$_POST['message']."

",
"From: ".$_POST['name']." <".$_POST['email'].">");


//dankwoordje

echo '<p align="center"><font color="#003366">Thanks !<br>Your message has been sent.<br> We will get back to you as soon as we can.</font></p>';

}

//Indien problemen
else{
echo '<p align="center"><font color="#FF0000">Please fill in all dates!</font></p><p><a href="contactEN.html">[back]</a>';

}
}
?>

Sorry, but nor your corrections, nor the one in the link seem to work. Is it maybe not a scripting problem ? Because sometimes I do receive all mails, and sometimes I don't.

Are you sure that the mail server settings are correct and your mail server works without any problem all the time.

Rather than using the simple mail function in the PHP you can install PEAR package that offers a mail sending in a much more efficient manner compared to the normal PHP method

Sometimes I receive the mails, sometimes I don't.

It's difficult to diagnose a problem like that remotely. Have you established if there are any patterns?

if ($_POST["Submit"]){

One should use the isset function to determine if elements are present before examining values. This applies to any data coming from the user. If nothing else, it avoids generating unnecessary log entries when elements are missing.

if ($_POST["name"] and $_POST["email"] and $_POST["subject"] and $_POST["message"] ){

You aren't actually going to validate the input before you use it? That's just asking for trouble!

"
Name: ".$_POST['name']."
E-mail: ".$_POST['email']."
Subject: ".$_POST['subject']."
Message: ".$_POST['message']."

"

Use escape sequences to include carriage returns and line feeds.

echo '<p align="center"><font color="#003366">Thanks !<br>Your message has been sent.<br> We will get back to you as soon as we can.</font></p>';

That markup is rather outdated. You might want to consider abandoning deprecated, presentation markup. This is the 21st century, after all.

Please guys, have a look !
My business depends on it !

Then wouldn't it be a better idea to use a pre-existing service that does work reliably, rather than reinventing the wheel (and making it square)?

Don't understand this ...

Didn't invent anything, that's why I ask your help in scripting, not your opinion. Guys, everyone that asks you something has a reason for it, and a idea behind it, that might might be hard to explain and to understand. Don't take this personally but sometimes I have a feeling that "professors" like to be in charge also of the feeling behind it.
My question was: why does that script not work, that's all. Don't need to know if you like the fact that I thank you for sending it. Don't judge. Never.

And if my business depends on it ? That was a "sales trigger" to get you answering. It worked ! But you couldn't resist...

Don't understand this ...

In your original post, you described an intermittent problem. Such problems may be caused by the system or its configuration, by user input, or some other awkward reason. Without being able to directly test it, such things can be difficult to solve. At the very least, you can determine if user input is a possible cause, particularly whether certain characters or character sequences occur during failure, but not during success.

Then wouldn't it be a better idea to use a pre-existing service that does work reliably, rather than reinventing the wheel (and making it square)?

Didn't invent anything,

"Reinventing the wheel" is phrase referring to the creation of something (anything) that already exists. The comment that followed, "making it square", is an observation that the reimplementation can often be worse than a previous incarnation: the notion of a "square wheel".

Reinventing the wheel can sometimes be a useful educational tool. However it can also be disastrous, especially in a situation such as this where security is a paramount concern.

that's why I ask your help in scripting, not your opinion.

You get what you pay for.

Guys, everyone that asks you something has a reason for it, and a idea behind it, that might might be hard to explain and to understand.

But they should try nevertheless. Too often, people ask the wrong questions. Rather than trying to find the best way of achieving something, they instead concentrate on a particular, often broken implementation that they think is best, regardless of whether it is or not.

Don't take this personally but sometimes I have a feeling that "professors" like to be in charge also of the feeling behind it.

Damn right. If someone wants to shoot themselves in the foot, I have no intention of giving them a loaded gun. Understanding why someone wants to do something provides the opportunity of dissuading them from doing silly things, as well as being able to suggest a better approach.

My question was: why does that script not work, that's all.

I've mentioned a couple of problems with the PHP code itself, one of which is of critical importance and might be indirectly responsible for the problem at hand. I've explained that providing a definitive reason for the behaviour observed may be difficult for any of us because we cannot examine the situation directly. I've also suggested a better course of action. What more do you want?

Don't need to know if you like the fact that I thank you for sending it.

Thank them, by all means. Just do it with decent markup.

Don't judge. Never.

So you'd prefer to remain ignorant of bad practice, hmm?

And if my business depends on it ? That was a "sales trigger" to get you answering. It worked ! ...

No, it didn't. My response would have been the same, whether it was for a business or not. A bad approach is a bad approach. However, if it were a mission-critical feature, surely that's all the more reason to use a tried-and-tested solution?

So, to get back to the point, if the above code doesn't work, it means that there is no coding problem, but an external problem (like hosting) ?
