I have the following :
<script charset="UTF-8">
function deleter(theid) {
var namme = document.getElementById(theid).id;
$.post( "sql_machine.php", {
selection_name: select_namme
})
}
</script>
using jquery, would it be possible to post a php array too? may be encoding it as json?
like the following?
<script charset="UTF-8">
function deleter(theid) {
var select_namme = document.getElementById(theid).id;
$.post( "sql_machine_tomskus.php", {
selection_name: select_namme,
{ array : dataToSend }
})
}
</script>
Just use JSON.stringify to send the array, and to decode it to array in php, use json_decode.
In JQ:
<script charset="UTF-8">
function deleter(theid) {
var select_namme = document.getElementById(theid).id;
$.post( "sql_machine_tomskus.php", {
selection_name: select_namme,
array : JSON.stringify(yourArrayOrObject)
})
}
</script>
Then, in php just use json_decode($_POST["array"])
thanksGINCHER here it is my final solution :
<script charset="UTF-8">
function deleter(theid) {
var select_namme = document.getElementById(theid).id;
$.post( "sql_machine.php", {
selection_name: select_namme,
array : <?echo json_encode($array);?>
})
}
</script>

I try to put data into js file, through "jquery $.post" and "fwrite php", and get back that data into array. How to do that?
here's the html:
<!doctype html>
<html>
<head>
<script src="https://code.jquery.com/jquery-2.1.4.js"></script>
<script>
$(document).ready(function() {
$("#button").click(function() {
if ($("#nameput").val() != "") {
$.post("processing.php", {
putname: $("#nameput").val()
});
var arr = [$.getScript("talk.js")];
alert(arr[0]);
}
})
})
</script>
</head>
<body>
<input type="text" id="nameput" />
<button id="button">send AJAX req</button>
</body>
</html>
Here's the php, I name it "processing.php" :
<?php
$file = fopen("talk.js","a");
$text = $_POST["putname"];
fwrite($file,'"'.$text.'",');
fclose($file);
?>
And "talk.js" will look like this :
"a","b","c",
Why I can't put that data from "talk.js" into array at " var arr = [$.getScript("talk.js")]; " as in html file above?
Here's what I try after I read comments. I change the scirpt into this:
<script>
$(document).ready(function() {
$("#button").click(function() {
if ($("#nameput").val() != "") {
$.post("processing.php", {
putname: $("#nameput").val()
}, function() {
$.getScript("talk.js", function(data) {
var arr = data.split(",");
alert(arr[0]);
})
})
}
})
})
</script>
And php into this:
<?php
$file = fopen("talk.js","a");
$text = $_POST["putname"];
fwrite($file,$text);
fclose($file);
?>
But it still not work?
here's a simplified version of your button click to help you out:
$("#button").click(function() {
$.getScript("talk.js", function(data){
var arr = data.split(',');
alert(arr[0]);
});
});
If you log the output of $.getScript you will easily see why what you're trying doesn't work.
Using this method you will get the data returned from the script ("a","b","c"), but you'll need to split it on a comma into an array. Then you can reference whichever part of the array you want.
Note that the each element of the array will have quotations around them.
I'm tryin to get a value in URL from php file via $.get(), here is the code:
PHP folder called 'jquery_con4.php':
echo (isset($_GET['req'])) ? 'found':'notfound';
JQuery called 'pass.js':
$.get('connection/jquery_con4.php', function(data){
alert(data);
});
the main folder called 'password_c.php' which include the javascript called 'pass.js' which has $.get but it shows me in note 'notfound', & if remove if echo, it shows be 'undefined index:req'
--- URL is: 'http://localhost/series/skyface/password_c.php?req=65yDq0zI39UcRSF'
Thanks!
http://localhost:8888/series/skyface/password_c.php?req=65yDq0zI39UcRSF
In order to pass the 'req' value from the URL querystring to the jquery_con4.php script, you need a JS function that will grab it for you and pass it into an ajax request.
Below is an example of how that might work.
/series/skyface/password_c.php
<!DOCTYPE html>

jQuery(document).ready(function($) {

I need help with putting this $id value into the javascript below
PHP:
<?php
$id = NULL;
$username = 'YouTube';
$xml = simplexml_load_file(sprintf('http://gdata.youtube.com/feeds/base/users/%s/uploads?alt=rss&v=2&orderby=published', $username));
if ( ! empty($xml->channel->item[0]->link) )
{
parse_str(parse_url($xml->channel->item[0]->link, PHP_URL_QUERY), $url_query);
if ( ! empty($url_query['v']) )
$id = $url_query['v'];
}
echo $id; // Outputs the video ID.
?>
JS: Need $id value ---> 'I need the value to go right here'
<script type="text/javascript">
$('document').ready(function() {
var options = { videoId: 'I need the value to go right here', start: 3 };
$('#video1').tubular(options);
});
</script>
Do something like this....
<script type="text/javascript">
$('document').ready(function() {
var options = { videoId: '<?php echo $id?>', start: 3 };
$('#video1').tubular(options);
});
</script>
But make sure, you are including this script in php file.
Other solution could be to use html hidden variable, and access that value using js.
by the use of
<script type="text/javascript">
....
</script>
I understand you're using javascript inside of your view! then why not just do this
var options = { videoId: '<?php echo $id; ?>', start: 3 };
Use
<script type="text/javascript">
var id= '<?= $id; ?>';
</script>
now you can use the id variable in your javascript
<script type="text/javascript">
$('document').ready(function() {
var options = { videoId: id, start: 3 }; // id variable which is filled by $ib variable of php
$('#video1').tubular(options);
});
</script>
I got a page with a form to fill it with custormers info. I got previous custormers data stored in a php array. With a dropdownlist users can fill the form with my stored data.
what i have is a jquery function that triggers when the value changes and inside that function i whould like to update the form values with my stored data (in my php array).
Problem is that i dont know how to pass my php array to the jquery function, any idea ??
this is how i fill the array:
$contador_acompanantes = 0;
foreach ($acompanantes->Persona as $acomp)
{
$numero = $acomp->Numero;
$apellidos = $acomp->Apellidos;
$nombre = $acomp->Nombre;
$ACOMPANANTES[$contador_acompanantes] = $ficha_acomp;
$contador_acompanantes++;
}
got my select object:
<select name="acompanante_anterior" id="acompanante_anterior">
<option value="1" selected>Acompañante</option>
<option value="2">acompanante1</option>
<option value="2">acompanante2</option>
</select>
and this is my code for the jquery function (it is in the same .php page)
<script type="text/javascript">
$(document).ready(function()
{
$('#acompanante_anterior').on('change', function()
{
});
});
</script>
var arrayFromPHP = <?php echo json_encode($phpArray); ?>;
$.each(arrayFromPHP, function (i, elem) {
// do your stuff
});
You'll likely want to use json_encode, embed the JSON in the page, and parse it with JSON-js. Using this method, you should be aware of escaping </script>, quotes, and other entities. Also, standard security concerns apply. Demo here: http://jsfiddle.net/imsky/fjEgj/
HTML:
<select><option>---</option><option>Hello</option><option>World</option></select>
<script type="text/javascript">
var encoded_json_from_php = '{"Hello":[1,2,3], "World":[4,5,6]}';
var json = JSON.parse(encoded_json_from_php);
</script>
jQuery:
$(function() {
$("select").change(function() {
$(this).unbind("change");
var val = json[$(this).val()];
var select = $(this);
$(this).empty();
$.each(val, function(i, v) {
select.append("<option>" + v + "</option>");
});
});
});
try this one..
<script type="text/javascript">
$(document).ready(function()
{
$('#acompanante_anterior').on('change', function()
{
my_array = new Array();
<?php foreach($array as $key->val)?>
my_array['<?php echo $key?>'] = '<?php echo $val;?>';
<?php endif; ?>
});
});
</script>
I just get the parameters from PHP GET method and use them using jQuery. There is no output when run the page.
<?php
if (isset($_GET['url'])){
$url = $_GET['url'];
$url = explode(" " , $url);
echo end($url);
exit;
}
?>

I'm new to designs and hope mistake is there.
First of all put your document in standards mode (by using a proper doctype at the beginning, which means HTML 4/XHTML 1 strict or HTML 5). Then you can use error console for debugging.
I found following error
Unexpected token: ':' on line 7,
The colon should be a semicolon.
var url = $(this).val():
And then, the actual reason why nothing is happening is because the input is non-existent when the script is invoked/cached. You need to execute it after the DOM has been constructed.
$(document).ready(function() {
// content
});
Final code.
$(document).ready(function() {
$('input[type=text]').change(function (){
if ($(this).val() !== ''){
var url = $(this).val();
$.post('grab.php?url='+url+'', function (data){
window.open(data, 'Download', 'width=10,height=10');
$(this).html('');
});
}
});
});
put it in $(document).ready() like this:
$(document).ready(function() {
$('input[type=text]').change(function (){
if ($(this).val() !== ''){
var url = $(this).val():
$.post('grab.php?url='+url+'', function (data){
window.open(data, 'Download', 'width=10,height=10');
$(this).html('');
});
}
});
});
I think using a .change event on a text input isn't advisable. Usually .blur and .focus are more appropriate.
$(document).ready(function() {
$('input[type=text]').blur(function(){
var currentInput = this;
if ($(currentInput ).val() != ''){
var url = $(currentInput ).val();
$.post('grab.php?url='+url, function(data){
window.open(data, 'Download', 'width=10,height=10');
$(currentInput).val('');
});
}
});
});
