Input Boxes and Loop???

[ali_2kool2002]

Hi ,, im really  ??? confused  as im trying to create several input boxes for the user to enter information but was wondeering if anyone can code in php something which would create say 3 input text boxes but when the user clicks submit ,, the data can be checked if someone has entered anything. I need to use a loop thought as a random number (x) is used to loop x times, so if x is 3 it should create 3 input boxes..

 

P.s. The problem i get when doing this in a loop is the name of the text box is always the same as it goes through a loop,

and so say i wana check if the input box is empty in one ofthe textboxes , the php script would only check if all the input boxes are empty as they have the same name...the if statement i use in the handling code is

 

if (empty($_POST[quantity])) 

 

for the code input text box

echo '<td align =\"left\"> <INPUT TYPE=\"TEXT\" name =\"$quantity\" >';

 

the variable quantity is from the input text name i am using but some how need 2 get the name of the submit to change each time it goes in the loop depending on how many times it needs to loop (ie x's value) ??? ??? ??? ??? ??? ???

You could do...

 

// make inputs

$inputs = 3;

$name = 'input';

for ( $x = 1; $x <= $inputs; $x += 1 )
{
echo '<td align="left"> <input type="text" name ="' . $name . '[' . $x . ']" />';
}

 

// process the inputs

if ( ! empty ( $_POST['input'] ) )
{
foreach ( $_POST['input'] AS $key => $value )
{
	echo '$input[' . $key . '] = ' . $value . ';<br />';
}
}

make the input box as array

 

<input type=text name=txtbox[]>

 

it will give you an array on the action page

something like this.

<?php
$rand = rand(1, 20);

for($i = 0; $i < $rand; $i++){
	echo "<input type=\"text\" name=\"inputfield". $i ."\" value=\"". $_POST['inputfield'. $i .''] ."\">\n";
}
?>

here u go a bit of a bum but done it have a test see what you think.

<?php

// echo the form.
echo"<form method='POST' action=''>";

//set array for the input names to echo.
$word=array("name","password","email");

// for loop 3 times and get the array. 
for($i=0; $i<3; $i++ && $word){
//echo the eords for the input boxs

//and show 4 input boxs via a array of result[].
echo"<br>$word[$i]<br>
<input type='text' name='result[]'>
<br>";
}

//show the submit box and close form.
echo"<br><input type='submit' name='submit'>
</form>";

//if the user press submit.
if($_POST['submit']){

//for loop the form for array result[].
for($i=0; $i<count($result); $i++){

//get varables to show if result exist.	
$name="name: ".$result[0]." ";
$password="password: ".$result[1]." ";
$email="name: ".$result[2]." ";
}

//if all data forom form  array[] exist. 
if($result[0] && $result[1] && $result[2]){

//echo the array[] set varables. 		
echo "<br>$name<br>$password<br>$email";

// else it result not exest. 	
}else{

// tell them that all the form must be filled in. 
echo "<br><br> sorry please fill in all the form"; 
}
}
?>
