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?
also how could i get the information added to be organized into colums?
$_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()
its like $movies = array ();
movies[1] = harold and kumar go to white castle;
movies[2] = blah...;
and so on
also i couldnt find an example of the in array function that finds the value enter all the examples find a set value.
You couldn't find an example of in_array()?
Or I don't think I get what you mean :blush:PHP Code:if(!in_array($_POST['blah']))
{
//add your value
}
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

does anyone know?
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.
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
}
uhh....wut did i say...lol....
I thought i was helpful.... i dont even remember posting to this... wierd...
Im just asking this... cuz i was away from computer and had this site open.
And i found my sister in here...
She likes to "make me say" "stupid" 'things'
if it was hurtful... i am sorry... and she will be punished(no net for a 3 weeks ^_^)
its ok lol and its not impolite if u say jk ;) i love you visual add and plagues my hero
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
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" />
um...
well if your questions made sense maybe we would understand...
Maybe um is his way of saying thanks for the help :thumb:
i dun understan d visual ads post and my quiestion does make sense...even if it didnt remix u clarified it for me
Could you elaborate a bit. I am not sure I understand what you mean. :confused:Quote:

what dont you get??PHP Code:if (! in_array($_POST['value'], $array)) {
$array[] = $_POST['value']; // add the value to the array
}
thje fact that wen i add a value atribute the name of that lets say value="movies" the word movies will show up in thew text box before anyone types anything in and i dont want that
I see why you are confused now. Forget about the value attribute in HTML, this sets the default value for the field. You need to use the name attribute - the nam,e you give a field in the name attribute will be the name you use to access it in your PHP.
HTML Code:<input type="text" name="music" />
PHP Code:if (! in_array($_POST['music'], $array)) {
$array[] = $_POST['music']; // add the value to the array
}
its still not workin for some reason
heres the code this might help alot more

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
shouldnt it be
PHP Code:if ((in_array($_POST['music'], $array))!=true) {
$array[] = $_POST['music']; // add the value to the array
}
that doesnt work either...y is something so simple so complicated lol
in_array() returns boolean, therefore:Quote:

if(!in_array($_POST['music'], $array))
//this would say if true
if(in_array($_POST['music'], $array))
But...this line here:
Shouldn't have the [] on movies, that would tell us it's an array, but that doesn't make much sense does it? And this line:Code:<input type = 'text' name = 'movies[]' value = 'movie' size = '50' /><br />
Wouldn't work, the first parameter is expecting a value, that would return Array. But anways, take the brackets off of movies, and out of that if statement, and see what happends.Code:if (! in_array($_POST['movies[]'], $movies))
.... :confused:Quote:
