post array

[Yohanne]

Hi coders,

 

i just want to display the each value of input text but i don't get it, any advice where i go wrong.. no database required.

<input type='text' name = 'val1[]' value='asasas'>
<input type='text' name = 'val2[]' value='asasas'>

<input type='text' name = 'val1[]' value='sdsddd'>
<input type='text' name = 'val2[]' value='sdsdsd'>

$value1 = $this->input->post('val1');
$value2 = $this->input->post('val2');
								
$array = array(value1, value2);
echo $comma_separated = implode(",", $array);

implode() isn't recursive. When you apply it to an array of arrays, you get nonsense.

 

Simply pass each array individually:

<?php

$values1 = ['foo', 'bar'];
$values2 = ['qux', 'quux'];

echo implode(',', $values1).' -- '.implode(',', $values2);

i already trying here, but don't get the logic.. and how do i get the value of input text. 

 

i mean is, where is the input text value here

I have given you an example of how to correctly display two arrays of values. Where those arrays come from is entirely irrlevant.

 

If you don't know how to get POST parameters in CodeIgniter, you're in the wrong forum. I can move your thread to the frameworks section.

Do you know if the value variables (eg. $value1) contain arrays? You could check using code like this:

echo '<pre>' . print_r($value1, true) . '</pre>';

Also note that the following line is missing dollar signs before the value variables:

$array = array(value1, value2);

And with the following line, do you expect a comma-separated list of both $value1 and $value2?

echo $comma_separated = implode(",", $array);

In other words, do you expect the following output:

asasas,sdsddd,asasas,sdsdsd

 

If so, you could use array_merge() to combine the arrays. More information can be found here:

http://php.net/manual/en/function.array-merge.php

 

 

Note that the following line just creates an array of arrays:

$array = array_merge($value1, $value2);
