[RESOLVED] arrays

**ninjanutz** · Sep 18th, 2005, 07:40 PM

im making an array that works off a form. i have a text box where i type the info and i want that info taken and added to the array and to bew included in my foreach loop. i also want the script to check to make sure wat im adding hasnt been added already. how would i do this?

**ninjanutz** · Sep 18th, 2005, 08:06 PM

also how could i get the information added to be organized into colums?

**{yak}** · Sep 18th, 2005, 08:44 PM

$_POST[] is an array. Maybe you can explain a little more? To check to see if a value is allready in an array, you can use in_array()

**ninjanutz** · Sep 18th, 2005, 08:57 PM

its like $movies = array ();
movies[1] = harold and kumar go to white castle;
movies[2] = blah...;

and so on

**ninjanutz** · Sep 18th, 2005, 09:09 PM

also i couldnt find an example of the in array function that finds the value enter all the examples find a set value.

**{yak}** · Sep 18th, 2005, 09:55 PM

You couldn't find an example of in_array()?

PHP Code:


if(!in_array($_POST['blah']))

{

    //add your value

}

Or I don't think I get what you mean

he wants to look thru an array, see if an element is in it, if not add it to the array. I only know because i spoke to him on AIM..i know..he speaks in gibberish :P

Oi - stoppit - if you arn't going to help then don't post and if you have nothing polite to say then don't bother either.

**visualAd** · Sep 22nd, 2005, 12:22 AM

Yes, you need the in_array function:

PHP Code:


/* test if value is in the array */

if (! in_array($_POST['value'], $array)) {

    $array[] = $_POST['value']; // add the value to the array

}

**ninjanutz** · Sep 22nd, 2005, 07:58 PM

wat can i add though to make sure it does it right adding the value atribute makes that malue appear in the box on startup

**visualAd** · Sep 23rd, 2005, 12:04 AM

The post index corresponds to the name attributes of the form elements. Therefore, the following HTML will cause the $_POST array to have a value1 index and a value2 index:

HTML Code:

<input name="value1" />
<input name="value2" />

**ninjanutz** · Sep 25th, 2005, 06:25 PM

um...

**|2eM!x** · Sep 25th, 2005, 06:40 PM

Could you elaborate a bit. I am not sure I understand what you mean.

**ninjanutz** · Sep 26th, 2005, 07:01 PM

ok lol i have a text input and i want it to take that value.. add it to the array called movies...and make sure that the value being added doesnt already exist in the array

**|2eM!x** · Sep 26th, 2005, 08:05 PM

PHP Code:


if (! in_array($_POST['value'], $array)) {

    $array[] = $_POST['value']; // add the value to the array

}

what dont you get??

**ninjanutz** · Sep 26th, 2005, 09:04 PM

thje fact that wen i add a value atribute the name of that lets say value="movies" the word movies will show up in thew text box before anyone types anything in and i dont want that

**visualAd** · Sep 27th, 2005, 12:41 AM

I see why you are confused now. Forget about the value attribute in HTML, this sets the default value for the field. You need to use the name attribute - the nam,e you give a field in the name attribute will be the name you use to access it in your PHP.

HTML Code:

<input type="text" name="music" />

PHP Code:


if (! in_array($_POST['music'], $array)) {

    $array[] = $_POST['music']; // add the value to the array

}

**ninjanutz** · Sep 28th, 2005, 08:46 PM

its still not workin for some reason

heres the code this might help alot more

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN">

<html xmlms='http://www.w3.org/1999/xhtml' xml:lang='en' lang='en'>

<html>
<head>

<title>Movie List</title>

</head>
<body>

<div id = "movies" align = "center">
<?php

if (isset ($_POST ['submit']))
{
	if (! in_array($_POST['movies[]'], $movies))     
	{
		$array[] = $_POST['movies[]']; 
    		echo "<p>Your movie has been added!<br />
    		<form action = 'movielist.php' method = 'post'>
           	<input type = 'text' name = 'movies[]' value = 'movie' size = '50' />
            	<input type = 'submit' name = 'submit' value = 'Enter Movie' />
            	</form>";
	} else {
			echo "<p>This movie has already been entered</p>
    			<form action = 'movielist.php' method = 'post'>
           	        <input type = 'text' name = 'movies[]' value = 'movie'  size = '50' />
            		<input type = 'submit' name = 'submit' value = 'Enter Movie' />
            		</form>";
	}

} else {

           echo "<form action = 'movielist.php' method = 'post'>
            <input type = 'text' name = 'movies[]' value = 'movie'  size = '50' /><br />
            <input type = 'submit' name = 'submit' value = 'Enter Movie' />
            </form>";

}

$movies = array ();
$movies[1] = blah;
$movies[2] = argh;

asort ($movies);

foreach ($movies as $movies => $movie)
{
  echo "$movie<br />\n";
}

?>
</div>

</body>
</html>

**ninjanutz** · Sep 28th, 2005, 08:47 PM

i no some of the code is "bad coding" but i really dun care as long as it worx its fine for wat i need it to do

**|2eM!x** · Sep 28th, 2005, 09:13 PM

shouldnt it be

PHP Code:


if ((in_array($_POST['music'], $array))!=true) {

    $array[] = $_POST['music']; // add the value to the array

}

**ninjanutz** · Sep 28th, 2005, 09:18 PM

that doesnt work either...y is something so simple so complicated lol

}

in_array() returns boolean, therefore:

PHP Code:


//this would say if not true, so false

if(!in_array($_POST['music'], $array))



//this would say if true

if(in_array($_POST['music'], $array))

See, there's no need for the == true or whatever, becuase either way it'll evaluate to true or false. I see I forgot the second parameter of in_array() in my post, good thing I posted the link to it though, right?

But...this line here:

Code:

 <input type = 'text' name = 'movies[]' value = 'movie'  size = '50' /><br />

Shouldn't have the [] on movies, that would tell us it's an array, but that doesn't make much sense does it? And this line:

Code:

if (! in_array($_POST['movies[]'], $movies))

Wouldn't work, the first parameter is expecting a value, that would return Array. But anways, take the brackets off of movies, and out of that if statement, and see what happends.
