Add information to textarea and save it in an array - php

Question

Is it possible to do this in PHP + CSS? Got a textarea with the result of an array inside it:
<textarea class="ta_scripts"><?php
foreach ($script as $script_launcher){
echo $script_launcher."\r\n";
}?></textarea><br><br>
The code below shows a textarea with something like this:
This is a beautiful line 1 from the array
This is a beautiful line 2 from the array
This is a more beautiful line 3 from the array
And so on.
So what I want is to add some text inside the textarea, then when click a submit button this text will be added to the array $scriptlauncher[]
If I wrote "this is my new text" then the result of textarea must be:
This is a beautiful line 1 from the array
This is a beautiful line 2 from the array
This is a more beautiful line 3 from the array
this is my new text
My first approach:
HTML and PHP and call to Javascript
<form name="frmscript" onsubmit="return false;">
<?php if (isset($_POST["script"])) {
$script = $_POST["script"];
}?>
<textarea class="ta_scripts" name="ta_scripts"><?php
foreach ($script as $script_launcher){
echo $script_launcher."\r\n";
}?>
</textarea><br><br>
<input type="button" name="execscript" value="Execute scripts" id="submit" onClick="addtext();" />
</form>
Javascript:
function addtext() {
var newtext = document.frmscript.ta_scripts.value;
document.frmscript.ta_scripts.value = "";
document.frmscript.ta_scripts.value += newtext;
window.location.href = "index.php?script=" + newtext;
}
Second Approach (can't save the new array yet)
HTML and PHP and call to Javascript:
<form name="frmscript" onsubmit="return false;">
<?php /*if (isset($_POST["script"])) {*/
if($_POST){
$script = json_decode($_POST["script"]);
}
?>
<textarea class="ta_scripts" name="ta_scripts"><?php
foreach ($script as $script_launcher){
echo $script_launcher."\r\n";
}?></textarea><br><br>
<input type="button" name="execscript" value="Execute scripts" id="submit" onClick="addtext();" />
</form>
Javascript:
function addtext() {
var script = document.frmscript.ta_scripts.value;
document.frmscript.ta_scripts.value = "";
document.frmscript.ta_scripts.value += script;
script = JSON.encode(script);
var miAjax = new Request({
url: "index4.php",
data: "script=" + script,
onSuccess: function(textResponse){
$('result').set("html", textResponse);
},
onFailure: function(){
$('result').set("html", "Error!!");
}
})
miAjax.send();
Third approach (Any help would be much appreciated!):
HTML and PHP:
<form name="frmscript" onsubmit="return false;">
<?php /*if (isset($_POST["script"])) {*/
if(isset($_GET['script'])){
$script = $_GET['script'];
}
?>
<textarea class="ta_scripts" name="ta_scripts"><?php
foreach ($script as $script_launcher){
echo $script_launcher."\r\n";
}?></textarea><br><br>
<input type="button" name="execscript" value="Exec script" id="submit" onClick="addtext();" />
</form>
Javascript:
$(document).ready(function () {
$('#execscript').click(function () {
/* var name_val = $('input[name="script"]').val();*/
var script = document.frmscript.ta_scripts.value;
$.ajax({
type: "GET",
url: "index4.php", //get response from this file
data: {
name: script
},
success: function (response) {
$("textarea#ta_scripts").val(response); //send response to textarea
}
});
});
});

I'm not sure I completely understand you, but in order to read lines into an array:
$text = trim($_POST['testtextarea']);
$textAr = explode("\n", $text);
$textAr = array_filter($textAr, 'trim'); // remove any extra \r characters left behind
foreach ($textAr as $line) {
//Push to scriptlauncher array.
array_push($scriptlauncher, $line);
}
I've not tested this, but it should put you on the right track.
