form submission to function

[netmastan]

I have a function that get parameters from a form then insert into database.

functions are at function.php

and form are at index.php.

How do u post the forms submission to a particular function( which is at function.php file)

[diego25]

In your form, have a hidden field like
<input type="hidden" name="action" value="insert">

And then in your functions.php page you do

if (isset($action) && $action == "insert") {
insert($_POST);
}

This works...

<?
function foo()
{
     echo $_POST['name'];
}
?>
<form action="" method="post">
<input type="text" name="name">
</form>
<?
if( $_POST['name'] )
{
     foo();
}
?>

thank you.. why the following code does not work.When i submit it bring the same form. The following code is in index.php file and my insert function is at function.php file.

<?php

include("modules/Directory/function.php");


if(!empty($submit)) {

insert($cat_id,$listname,$shortdesc,$desc,$addr,$suburb,
$postcode,$city,$phone,$mobile,$fax,$email,$website);

} else {


echo "<center><font class=\"title\"><b>Adding your listing under $catname</b></font></center><br><br>";

echo "<form  action='' method=\"post\">"
."<input type=\"hidden\" name=\"action\" value=\"insert\">"
."Name: <input type=\"text\" name=\"listname\" size=\"40\" maxlength=\"100\"><br>";
echo "Short Description<br><textarea name=\"shortdesc\" cols=\"60\" rows=\"8\"></textarea><br><br>";
echo "Extended Description<br><textarea name=\"desc\" cols=\"60\" rows=\"8\"></textarea><br><br>"
."Address <input type=\"text\" name=\"addr\" size=\"50\" maxlength=\"60\"><br>"
."Suburb: <input type=\"text\" name=\"suburb\" size=\"50\" maxlength=\"60\"><br>"
."Postcode: <input type=\"text\" name=\"postcode\" size=\"30\" maxlength=\"60\"><br>"
."City";
echo"

."</form>";
}
?>

use isset instead of empty

if(isset($submit)) {

also you havnt put in post vars etc. you will need to do this for every var posted
$submit = $_POST['submit'];

[netmastan]

Well.. when I use switch statment..it's work great...I just want to keep the functions in separate file.

What's the difference between

<?
// insert function here
//forms here 


switch($action) {

default:
index();
break;


case "Add":
insert($cat_id,$listname,$shortdesc,$desc,$addr,$suburb,$postcode,$city,$phone,$mobile,$fax,$email,$website);
break;

}
?>

what's the difference between "if(isset($submit))" and "if(!empty($submit))"

when you submit form variable $cat_id,$listname etc automatically pick up from the forms.(cat_id,listname)

[Duey]

if you are using a later version of php you MUST use $POST/$GET or it will not work

[Weedpacket]

What Duey said. Use the modern form variable arrays. Otherwise, to use all your form variables inside a function, you'll have to pass them all to the function explicitly - otherwise they won't have any values there. The $POST[] $GET[] (and $_FILE[]) arrays will always contain the values of submitted forms wherever in the script they're used. The same can't be said of other ways of accessing form variables.

[netmastan]

Still the same, once i submit the form it bring the same form....so i guess there is a problem for form action.

<?php

include("modules/Directory/function.php");


if(isset($_POST['submit'])) {

insert($_POST[cat_id],$_POST[listname],$_POST[shortdesc],
$_POST[desc],$_POST[addr],$_POST[suburb],$_POST[postcode],$_POST[city],$_POST[phone],$_POST[mobile],$_POST[fax],$_POST[email],$_POST[website]);

}  else {


echo "<center><font class=\"title\"><b>Adding your listing under $catname</b></font></center><br><br>";

echo "<form  action='modules.php?name=Directory&file=index' method=\"post\">"

."Name: <input type=\"text\" name=\"listname\" size=\"40\" maxlength=\"100\"><br>"
echo "Short Description<br><textarea name=\"shortdesc\" cols=\"60\" rows=\"8\"></textarea><br><br>";
echo "Extended Description<br><textarea name=\"desc\" cols=\"60\" rows=\"8\"></textarea><br><br>"
."Address <input type=\"text\" name=\"addr\" size=\"50\" maxlength=\"60\"><br>"
."Suburb: <input type=\"text\" name=\"suburb\" size=\"50\" maxlength=\"60\"><br>"
."Postcode: <input type=\"text\" name=\"postcode\" size=\"30\" maxlength=\"60\"><br>"
."City";
echo"

function insert function which is in function.php file

function insert($cat_id,$listname,$shortdesc,$desc,$addr,$suburb,$postcode,
$city,$phone,$fax,$mobile,$email,$website)
	{
	global $dbi;
		$result=mysql_query("insert into dir_list values (NULL, '$cat_id','$listname','$shortdesc','$desc','$addr','$suburb','$postcode','$city','$phone','$mobile','$fax','$email','$website')", $dbi);
			if(! $result)
				die ("Insert Listing Error : ".mysql_error());

}

[diego25]

You have nothing named 'submit' in your form! You have a submit button, but it's not named 'submit'...so just name it 'submit' and it should work.

i.e.
<input type="submit" name="submit">
