[SOLVED] Editing info in an array

[cheechm]

Hello,

I was just wondering:

Say I have an array like so (in lang.php)

$lang = array (

[welcome]  => Welcome to the site

);

 

How would I be able to insert that into a text field in a another file say admin.php and then be able edit the "Welcome to the Site" bit and save it?

 

Thanks

$lang['welcome']= "New data";

 

mis-read

 

your need to write the whole PHP file again.. kinda bad idea.. a database would be better..

why would you want to do this ?

Sorry I misread the question

 

lang.php

<?php

$lang = array('welcome' => 'Welcome to site',
              'other_message' => 'Some other message'
              );

?>

 

admin.php

<?php
include('lang.php');

echo $lang['welcome'];
echo $lang['other_message'];

?>

MadTechie isn't it a quite common way to deal with multiple languages in php applications? All he needs is a lang.php with language for the site and lang_admin.php with language for the admin part.

[MadTechie]

the 2 ways i use are

#1 a database (easy)

#2 many files (one for each language)

 

on option 2, your only need to write the array contents

<?php

$lang = array('welcome' => 'Welcome to site',
              'other_message' => 'Some other message'
              );

?>

 

but still its the whole file.. if its a configuration file, then its a bad idea, if its just the language file, then thats fine.. unless its going to happen many times (multiple people opening the file at ones will cause major problems)

 

thats way i asked why they are doing it

 

Personally when i language files, i write one in English and send that to be translated to XYZ languages, if the customer whats to change it themselfs i nomally go for a database..

 

of course if its a short amount of text then one file is fine, i just put all  the arrays into thats file, but the idea is still the same.

 

[cheechm]

It is just gonna be in English. It is a custom CMS.

It will only ever be short amount of text. However how would I pull it from the array and post it in a text field where the user can edit it then save it back to the array?

 

Thanks

[MadTechie]

your probably have tp do something like this

 

<?php
$filename = 'lang.php';
include $filename;

$handle = fopen($filename, "r");
$contents = fread($handle, filesize($filename));
fclose($handle);

$NewLang = $lang;
//update NewLang
//ie 
$NewLang['Extra'] = "New Data";

$NewContents = "";
$NewArray = "";

foreach($NewLang as $K => $V)
{
$NewArray .= "\"$K\" = \"$V\", ";
}
$NewArray = trim($NewArray, ",");

$NewContents = '<?php';
$NewContents = '$lang = array(';
$NewContents .= $NewArray;
$NewContents .= ')';
$NewContents .= '?>';

//write back to file
if (is_writable($filename)) {
    if (!$handle = fopen($filename, 'w')) {
         echo "Cannot open file ($filename)";
         exit;
    }
    if (fwrite($handle, $NewContents ) === FALSE) {
        echo "Cannot write to file ($filename)";
        exit;
    }
    fclose($handle);
}
}
?>

Thanks very much for that.

That looks like it is just creating new ones, how would I update them?

Thanks

[MadTechie]

thats for the update

 

just read the array into form elements and to update run a script like the above example

 

to add elements your need to update this part

//update NewLang
//ie 
$NewLang['Extra'] = "New Data";

[cheechm]

Sorry. 

 

How would I put it in form elements and what IDs would I need to give the form elements?

 

Thanks 

[MadTechie]

you sure you want to do it this way.. a database it easier to manage..

 

i don't have time to explain it at the moment

 

if you can write a form and post it, i'll try to get some time in the morning (i'm in the UK) and write a basic versioin

[cheechm]

I suppose it could be easier in a database however then each time I want to call it would I have to use $row[Data]?

 

Thanks

[MadTechie]

true, but you could have the lang.php file open the database and create the array and then refer to that. so it would still seam exactly the same as having the array you suggested

[cheechm]

Here is a form:

 

<form name='Language' action='lang.php' method='POST' id="lang">
<input type='text' name='data' id='data' size='45' value=''>
</form>

 

How would I be able to insert into that?

Also how could I write the array name before the input type so for instance if it is the welcome message it would display "Welcome"?

 

Thanks

[cheechm]

Anyone else?

[darkfreaks]

<?php

$lang = array('welcome' => 'Welcome to site',
              'other_message' => 'Some other message'
              );

?>

<?php echo $lang; ?><form name='Language' action='lang.php' method='POST' id="lang">
<input type='text' name='data' id='data' size='45' value=''>
</form>

[cheechm]

Does that insert the welcome message into the text input?

Thanks

[darkfreaks]

you want it in the input?and no it will display it before the input

 

<input type='text' name='data' id='data' size='45' value='<?php echo $lang; ?>'>

[MadTechie]

erm.. no

it would be

<input type='text' name='data' id='data' size='45' value='<?php echo $lang['welcome']; ?>'>

 

[cheechm]

Ok. Thanks MadTechie and darkfreaks

 

[darkfreaks]
