Stream line $_POST

[denoteone]

I have 43 input  text boxes that I am going to name  box0 box1, box2 and so on. is there a trick I can use to assign them once I submit the form.  so that I don't have to do  $box_1 = $_POST['box1']; some sort of loop and then I am going to have to insert the values into a mySQL database.

 

Any help would be awesome.

you could do 1 of two things: a) you can name then all "box[]" and then access them as an array, or you can create dynamic variables using ${}

OK I will do it as an array. so all the inputs should be named box[] ?  do I have to create and array like flash?

so would my code look something like this

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

for($i = 0, $i <= 43,$i ++){
$box.$i = box[i];
}

}

form:

 

<input type="text" name="box[]" value="box0" />

 

and so on for each <input>...

 

now, $_POST['box'] is an array.  use appropriate array functions to manipulate the values to suit your needs.

if box[] is your HTML array, you could access each individual element like so

 

echo $_POST['box'][5];//the sixth text box

 

you could loop through the whole array like so

for ($i = 0; $i < count($_POST['box']); $i++){
echo $_POST['box'][$i];
}

//OR

foreach($_POST['box'] as $box){
echo $box;
}

so would my code look something like this

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

for($i = 0, $i <= 43,$i ++){
$box.$i = box[i];
}

}

 

Don't do that. What if one day you added another checkbox, or took one away? Chances are you won't find the error when you define 43 like that.

I am stuck in an infinite loop and I am getting an undefined error

 

if(isset($_POST['submit'])){
for ($i = 0; $i < count($_POST['box']); $i++){
$box.$i = $_POST['box'][$i];
echo $box.$i;
}

[mikesta707]

post the error? assuming your $_POST['box'] array isn't infintely long that for loop wouldn't cause an infinite loop

Looks like you want to do something like this?

 

if(isset($_POST['submit'])){
for ($i = 0; $i < count($_POST['box']); $i++){
${'box_' . $i} = $_POST['box'][$i];
echo ${'box_' . $i};
}

 

Variables will then be like $box_0, $box_1, etc..
