(noob here)

am trying to make a seperate function for an input form and a submit button form

then i wanna use the both function in an index file and it should output whatever i input inside the form

here's the code of my index file


<?php


require("includes/formfunctions.inc.php");

inputform($input);
submitbutton($input);
if($_GET['$input'] == '$submit')
{
  echo $input;
}



?>

at the bottom are the 2 functions saved as formfunctions.inc.php

here's the submit button function code

<?php
function submitbutton()
{
echo "<form>";
echo "<input type='submit' name='$submit' value='send'>";
echo "</form>";
return $input;
}
?>

here's the input form function code

<?php
function inputform($input)
{
echo "<form>";
echo "<input type='text' name='$input' size='10'>";
echo "</form>";
return $input;
}
?>

Have you checked out the require path ??

You've set it up quite strange... Your passing a variable $input to both functions, yet only one of the functions accepts a parameter.

Also, you have two form tags, both with no action or method attribute and in your code you're using $_GET.

Try something like this, all in the one file:

<?php

//First we will check if the submit button has been hit
if(isset($_POST['submit'])){
//Yes, it's been pressed.

echo $_POST['text']; //lets echo out what they wrote in the field called text

}else{
//Well, no submit button was pressed.
//So lets show the form.

//The $_SERVER['REQUEST_URI'] just gets the link to the page they are on.
echo <<<html
<form action="{$_SERVER['REQUEST_URI']}" method="post">
<input type="text" name="text" id="text"><br />
<input type="submit" name="submit" id="submit">
</form>
html;
}

?>

Its really quite unclear what your trying to do. You functions use variables which are not declared, they return values you never use, then your calling code does much the same. Also, your submit buitton must be within the same <form> in order to send the actual form.

Lets try a simpler example.

<?php

function form() {
 echo "<form>";
 echo "  <input type='text' name='input' size='10'>";
 echo "  <input type='submit' name='submit' value='send'>";
 echo "</form>";

}

if (isset($_GET['submit'])) {
 echo $_GET['input'];
} else {
 form();
}

?>
