How to create PHP email form with optional file attachment field - php

Question

I was testing a PHP Form for my client, when I realized that file attachment wasn´t optional, I have the full code here (it´s pretty long). Form works fine, but if you don´t choose any file, the e-mail will never arrive to it´s destination. I want to send the mail anyway and receive it without the attach.
I´m using PHP and jForm for validation.
Here is the input tag for file attaching (there to many input tags at the form.php file to list them here)
<input type="file" name="adjunto" id="adjunto">
And here is the send.php file (the true form is too long to publish here, i´m writing a shorter version of it)
<?php
// THE USER CHOOSES FROM A JOB LIST
$busqueda = $_POST["busqueda-list"];
$cargo = $_POST["cargo-list"];
// FILLS PERSONAL INFORMATION
$nombre = $_POST["nombre"];
$apellido = $_POST["apellido"];
$sexo = $_POST["sexo-list"];
// WE STYLE A MESSAGE WITH LOTS OF INPUTS
$mensaje = 'In the real form here is a table with lots of input styled';
// AND THEN WE ATTACH (in spanish spells adjunto)
$adjunto_name=$_FILES["adjunto"]["name"];
$adjunto_type=$_FILES["adjunto"]["type"];
$adjunto_size=$_FILES["adjunto"]["size"];
$adjunto_temp=$_FILES["adjunto"]["tmp_name"];
// IF THERE IS A FILE ATTACHED
if (is_uploaded_file($adjunto_temp))
{if($adjunto_type=="application/octet-stream" or $adjunto_type=="text/plain" or $adjunto_type=="application/msword" or $adjunto_type=="application/vnd.openxmlformats-officedocument.wordprocessingml.document" or $adjunto_type=="application/pdf" )
{
// MEET THE HEADERS
$headers = "MIME-Version: 1.0\n";
$headers .= "Content-type: text/html; charset=iso-8859-1\n";
$headers .= "From: ".$email."\n";
// MAIL HEADERS with attachment
$fp = fopen($adjunto_temp, "rb");
$file = fread($fp, $adjunto_size);
$file = chunk_split(base64_encode($file));
$num = md5(time());
// Normal headers
$headers = "From: ".$email."\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: multipart/mixed; ";
$headers .= "boundary=".$num."\r\n";
$headers .= "--$num\r\n";
// This two steps to help avoid spam
$headers .= "Message-ID: <".gettimeofday()." TheSystem#".$_SERVER['SERVER_NAME'].">\r\n";
$headers .= "X-Mailer: PHP v".phpversion()."\r\n";
// With mensaje
$headers .= "Content-Type: text/html; charset=iso-8859-1\r\n";
$headers .= "Content-Transfer-Encoding: 8bit\r\n";
$headers .= "".$mensaje."\n";
$headers .= "--".$num."\n";
// Attachment headers
$headers .= "Content-Type:".$adjunto_type." ";
$headers .= "name=\"".$adjunto_name."\"r\n";
$headers .= "Content-Transfer-Encoding: base64\r\n";
$headers .= "Content-Disposition: attachment; ";
$headers .= "filename=\"".$adjunto_name."\"\r\n\n";
$headers .= "".$file."\r\n";
$headers .= "--".$num."--";
// WE SEND MAIL WITH HEADERS
#mail("name#example.com", "".$busqueda." ".$cargo."", $mensaje, $headers);
fclose($fp);
}
// IF NOT, JUST SEND MAIL
else
#mail("ezemosho#gmail.com", "".$busqueda." ".$cargo."", $mensaje);
}
?>
Please I need a hand with this, I´m doing my best (i´ve already search here and other forums) and I think this maybe a problem many people had before!
Thank you!

Answer 1

you need to give one more condition on top
if (is_uploaded_file($adjunto_temp)) {
if($adjunto_type=="application/octet-stream" or $adjunto_type=="text/plain" or $adjunto_type=="application/msword" or $adjunto_type=="application/vnd.openxmlformats-officedocument.wordprocessingml.document" or $adjunto_type=="application/pdf" )
{
........... // your other stuff with respect to headers
#mail("name#example.com", "".$busqueda." ".$cargo."", $mensaje, $headers);
}
}
else
#mail("name#example.com", "".$busqueda." ".$cargo."", $mensaje);
now the mail will go on both conditions.
UPDATED WITH YOUR CODE
if (is_uploaded_file($adjunto_temp))
{
if($adjunto_type=="application/octet-stream" or $adjunto_type=="text/plain" or $adjunto_type=="application/msword" or $adjunto_type=="application/vnd.openxmlformats-officedocument.wordprocessingml.document" or $adjunto_type=="application/pdf" )
{
// MEET THE HEADERS
$headers = "MIME-Version: 1.0\n";
$headers .= "Content-type: text/html; charset=iso-8859-1\n";
$headers .= "From: ".$email."\n";
// MAIL HEADERS with attachment
$fp = fopen($adjunto_temp, "rb");
$file = fread($fp, $adjunto_size);
$file = chunk_split(base64_encode($file));
$num = md5(time());
// Normal headers
$headers = "From: ".$email."\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: multipart/mixed; ";
$headers .= "boundary=".$num."\r\n";
$headers .= "--$num\r\n";
// This two steps to help avoid spam
$headers .= "Message-ID: <".gettimeofday()." TheSystem#".$_SERVER['SERVER_NAME'].">\r\n";
$headers .= "X-Mailer: PHP v".phpversion()."\r\n";
// With mensaje
$headers .= "Content-Type: text/html; charset=iso-8859-1\r\n";
$headers .= "Content-Transfer-Encoding: 8bit\r\n";
$headers .= "".$mensaje."\n";
$headers .= "--".$num."\n";
// Attachment headers
$headers .= "Content-Type:".$adjunto_type." ";
$headers .= "name=\"".$adjunto_name."\"r\n";
$headers .= "Content-Transfer-Encoding: base64\r\n";
$headers .= "Content-Disposition: attachment; ";
$headers .= "filename=\"".$adjunto_name."\"\r\n\n";
$headers .= "".$file."\r\n";
$headers .= "--".$num."--";
// WE SEND MAIL WITH HEADERS
#mail("name#example.com", "".$busqueda." ".$cargo."", $mensaje, $headers);
fclose($fp);
}
}
// IF NOT, JUST SEND MAIL
else
{
// MAIL HEADERS
$headers = "MIME-Version: 1.0\n";
$headers .= "Content-type: text/html; charset=iso-8859-1\n";
$headers .= "From: ".$email."\n";
// This two steps to help avoid spam
$headers .= "Message-ID: <".gettimeofday()." TheSystem#".$_SERVER['SERVER_NAME'].">\r\n";
$headers .= "X-Mailer: PHP v".phpversion()."\r\n";
#mail("ezemosho#gmail.com", "".$busqueda." ".$cargo."", $mensaje);
}

Answer 2

Put the else statement for your first if condition, in your code you are using else for the condition2.
if (condition1) {
if (condition2) {
.........
.........
}
} else {
}
