We Keep Coding

With one button I want to call a php function as well as a javascript function?

I have a file, where i use a button, called MP4 Quality, When i click on that button, it opens a pop-up and ask for another button to press, to download the video, There is javascript with first button, and when it clicks, open the pop-up and give the second button, from where PHP is used, now i want it to download on single click,
Following is the code for first button...
<button id="videoDownloadButton" type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal" onClick="downloadVideo();">MP4 Quality</button>
and when it click, the following javascript code will run
function downloadVideo() {
var videoID = player.getVideoData()['video_id']
document.getElementById("downloadFormatList").innerHTML="Please wait. Processing...";
if (window.XMLHttpRequest) {
// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp3 = new XMLHttpRequest();
} else { // code for IE6, IE5
xmlhttp3 = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp3.onreadystatechange=function() {
if (xmlhttp3.readyState==4 && xmlhttp3.status==200) {
document.getElementById("downloadFormatList").innerHTML=xmlhttp3.responseText;
}
}
//keyword = keyword.replace(/ /g, '%2B');
xmlhttp3.open("GET","TMB/download.php?videoid="+videoID,true);
xmlhttp3.send();
}
and after that PHP code will run, PHP code is this...
if(isset($_REQUEST['videoid'])) {
$my_id = $_REQUEST['videoid'];
if(strpos($my_id,"https://youtu.be/") !== false)
{
$my_id = str_replace("https://youtu.be/","",$my_id);
}
}
<?php
//$my_video_info = 'http://www.youtube.com/get_video_info?&video_id='. $my_id;
$my_video_info = 'http://www.youtube.com/get_video_info?&video_id=' . $my_id . '&asv=3&el=detailpage&hl=en_US'; //video details fix *1
$my_video_info = curlGet($my_video_info);
/* TODO: Check return from curl for status code */
$thumbnail_url = $title = $url_encoded_fmt_stream_map = $type = $url = '';
parse_str($my_video_info);
?>
<?php
$my_title = $title;
$cleanedtitle = clean($title);
if (isset($url_encoded_fmt_stream_map)) {
/* Now get the url_encoded_fmt_stream_map, and explode on comma */
$my_formats_array = explode(',', $url_encoded_fmt_stream_map);
if ($debug) {
echo '<pre>';
print_r($my_formats_array);
echo '</pre>';
}
} else {
echo '<p>No encoded format stream found.</p>';
echo '<p>Here is what we got from YouTube:</p>';
echo $my_video_info;
}
if (count($my_formats_array) == 0) {
echo '<p>No format stream map found - was the video id correct?</p>';
exit;
}
/* create an array of available download formats */
$avail_formats[] = '';
$i = 0;
$ipbits = $ip = $itag = $sig = $quality = '';
$expire = time();
foreach ($my_formats_array as $format) {
parse_str($format);
$avail_formats[$i]['itag'] = $itag;
$avail_formats[$i]['quality'] = $quality;
$type = explode(';', $type);
$avail_formats[$i]['type'] = $type[0];
$avail_formats[$i]['url'] = urldecode($url) . '&signature=' . $sig;
parse_str(urldecode($url));
$avail_formats[$i]['expires'] = date("G:i:s T", $expire);
$avail_formats[$i]['ipbits'] = $ipbits;
$avail_formats[$i]['ip'] = $ip;
$i++;
}
echo '<div class="format_list">';
echo '<br>';
echo '<table>';
/* now that we have the array, print the options */
for ($i = 0; $i < 1; $i++) {
if ($config['VideoLinkMode'] == 'direct' || $config['VideoLinkMode'] == 'both')
?> <tr><td><?php
echo $avail_formats[$i]['type'];
?></td>
<td><small>(<?php
echo $avail_formats[$i]['quality'];
?>)</small> </td>
<td><small><span class="size"><?php
echo formatBytes(get_size($avail_formats[$i]['url']));
?></span></small>
</td>
<td><a href="<?php
echo $avail_formats[$i]['url'];
?> '&title='<?php
echo $cleanedtitle;
?>'" class="downloadButton">Record Video</a></td>
</tr>
<?php
}
?>
after the click on first button, this button will appear,
Record Video
Now i want it on single click, how can i do...??

Try adding this in the bottom of your pop-up page:
<script>
window.location = '<?php echo $avail_formats[$i]['url']; ?>';
</script>

According to your php code, the "second button" term is not correct.
You might have a count of second buttons which have different quality.
This is why the php code and second click exist.
If you want to download your video immediately, replace your foreach loop in php code
foreach ($my_formats_array as $format) {
parse_str($format);
$avail_formats[$i]['itag'] = $itag;
$avail_formats[$i]['quality'] = $quality;
$type = explode(';', $type);
$avail_formats[$i]['type'] = $type[0];
$avail_formats[$i]['url'] = urldecode($url) . '&signature=' . $sig;
parse_str(urldecode($url));
$avail_formats[$i]['expires'] = date("G:i:s T", $expire);
$avail_formats[$i]['ipbits'] = $ipbits;
$avail_formats[$i]['ip'] = $ip;
$i++;
}
on the
if (isset($my_formats_array[0])) {
parse_str($my_formats_array[0]);
header("Location: " . urldecode($url) . '&signature=' . $sig);
die();
}
And get rid of other unnecessary things

Open URL automatically without any click in PHP script

I have written a php script that is used to download any youtube video, it works on 2 buttons, first button is used to create the formats and second button starts downloading,
I want that if i press, first button, 2nd button, automatically did its work, and start download on single click,
Here is the code for first button,
<button id="videoDownloadButton" type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal" onClick="downloadVideo();">MP4 Quality</button>
Javssript on that button is....
function downloadVideo() {
var videoID = player.getVideoData()['video_id']
document.getElementById("downloadFormatList").innerHTML="Please wait. Processing...";
if (window.XMLHttpRequest) {
// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp3 = new XMLHttpRequest();
} else { // code for IE6, IE5
xmlhttp3 = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp3.onreadystatechange=function() {
if (xmlhttp3.readyState==4 && xmlhttp3.status==200) {
document.getElementById("downloadFormatList").innerHTML=xmlhttp3.responseText;
}
}
//keyword = keyword.replace(/ /g, '%2B');
xmlhttp3.open("GET","TMB/download.php?videoid="+videoID,true);
xmlhttp3.send();
}
and after that PHP script will work and produce that second button, Which is a HTML tag,
if(isset($_REQUEST['videoid'])) {
$my_id = $_REQUEST['videoid'];
if(strpos($my_id,"https://youtu.be/") !== false)
{
$my_id = str_replace("https://youtu.be/","",$my_id);
}
}
<?php
//$my_video_info = 'http://www.youtube.com/get_video_info?&video_id='. $my_id;
$my_video_info = 'http://www.youtube.com/get_video_info?&video_id=' . $my_id . '&asv=3&el=detailpage&hl=en_US'; //video details fix *1
$my_video_info = curlGet($my_video_info);
/* TODO: Check return from curl for status code */
$thumbnail_url = $title = $url_encoded_fmt_stream_map = $type = $url = '';
parse_str($my_video_info);
?>
<?php
$my_title = $title;
$cleanedtitle = clean($title);
if (isset($url_encoded_fmt_stream_map)) {
/* Now get the url_encoded_fmt_stream_map, and explode on comma */
$my_formats_array = explode(',', $url_encoded_fmt_stream_map);
if ($debug) {
echo '<pre>';
print_r($my_formats_array);
echo '</pre>';
}
} else {
echo '<p>No encoded format stream found.</p>';
echo '<p>Here is what we got from YouTube:</p>';
echo $my_video_info;
}
if (count($my_formats_array) == 0) {
echo '<p>No format stream map found - was the video id correct?</p>';
exit;
}
/* create an array of available download formats */
$avail_formats[] = '';
$i = 0;
$ipbits = $ip = $itag = $sig = $quality = '';
$expire = time();
foreach ($my_formats_array as $format) {
parse_str($format);
$avail_formats[$i]['itag'] = $itag;
$avail_formats[$i]['quality'] = $quality;
$type = explode(';', $type);
$avail_formats[$i]['type'] = $type[0];
$avail_formats[$i]['url'] = urldecode($url) . '&signature=' . $sig;
parse_str(urldecode($url));
$avail_formats[$i]['expires'] = date("G:i:s T", $expire);
$avail_formats[$i]['ipbits'] = $ipbits;
$avail_formats[$i]['ip'] = $ip;
$i++;
}
echo '<div class="format_list">';
echo '<br>';
echo '<table>';
/* now that we have the array, print the options */
for ($i = 0; $i < 1; $i++) {
if ($config['VideoLinkMode'] == 'direct' || $config['VideoLinkMode'] == 'both')
?> <tr><td><?php
echo $avail_formats[$i]['type'];
?></td>
<td><small>(<?php
echo $avail_formats[$i]['quality'];
?>)</small> </td>
<td><small><span class="size"><?php
echo formatBytes(get_size($avail_formats[$i]['url']));
?></span></small>
</td>
<td><a href="<?php
echo $avail_formats[$i]['url'];
?> '&title='<?php
echo $cleanedtitle;
?>'" class="downloadButton">Record Video</a></td>
</tr>
<?php
}
?>
This is the button, that i want to did its work automatically
<a href="<?php
echo $avail_formats[$i]['url'];
?> '&title='<?php
echo $cleanedtitle;
?>'" class="downloadButton">Record Video</a>

try this instead of your second button code.
header('Location:' .$avail_formats[$i][url]. '&title=' .$cleanedtitle);

Any event handlers attached with .on() or one of its shortcut methods are triggered when the corresponding event occurs. They can be fired manually, however, with the .trigger() method. A call to .trigger() executes the handlers in the same order they would be if the event were triggered naturally by the user:
$( "#foo" ).on( "click", function() {
alert( $( this ).text() );
});
if($("required-button").length>0){
$( "#foo" ).trigger( "click" );
}

Javascript delete isn't working

My delete function isn't working.
This is my table with the delete button.
// retrieve table contents
while ($row = $stmt->fetch(PDO::FETCH_ASSOC)){
extract($row);
//creating new table row per record
echo "<tr>";
echo "<td class='text-align-center'><input type='checkbox' name='item[]' class='checkboxes' value='{$employeeid}' /></td>";
echo "<td>{$name}</td>";
echo "<td>{$title}</td>";
echo "<td>{$phone}</td>";
echo "<td>{$supplier_name}</td>";
echo "<td>{$created}</td>";
echo "<td>";
// update record
echo "<a href='update_product.php?employeeid={$employeeid}' class='btn btn-info margin-right-1em'>";
echo "<span class='glyphicon glyphicon-edit'></span> Rediger";
echo "</a>";
// delete record
echo "<a delete-employeeid='{$employeeid}' delete-file='delete_product.php' class='btn btn-danger delete-object'>";
echo "<span class='glyphicon glyphicon-remove'></span> Slet";
echo "</a>";
echo "</td>";
echo "</tr>";
}
//end table<br>
echo "</table>";
This is my delete function
// delete single record
$(document).on('click', '.delete-object', function(){
// php file used for deletion
var delete_file = $(this).attr('delete-file');
var id = $(this).attr('delete-id');
var q = confirm("Are you sure?");
if (q == true){
$.post(delete_file, {
object_id: id
}, function(data){
location.reload();
}).fail(function() {
alert('Unable to delete.');
});
}
return false;
});
I got the code from a tutorial that I modified a lot. Everything else is working, except the delete function.
PHP CODE
<?php
// check if value was posted
if($_POST){
// include database and object file
include_once 'config/database.php';
// delete query
$query = "DELETE FROM employeestest WHERE employeeid = ?";
$stmt = $con->prepare($query);
$stmt->bindParam(1, $_POST['object_employeeid']);
if($stmt->execute()){
// redirect to read records page and
// tell the user record was deleted
echo "Medarbejderen er slettet.";
}else{
echo "Medarbejderen kunne ikke slettes.";
}
}
?>

Change
var id = $(this).attr('delete-Id');
to
var id = $(this).attr('delete-employeeid');
And, Change $.post to $.ajax as i've given
<script>
$(document).on('click', '.delete-object', function(){
var delete_file = $(this).attr('delete-file');
var id = $(this).attr('delete-employeeid');
var q = confirm("Are you sure?");
if (q == true)
{
$.ajax({url:delete-file,cache:false,success:function(result){
alert('Successfully Deleted');
}});
}
return false;
});
</script>

Maybe you just made grammar mistake
'delete-id' => 'delete-employeeid'

ajax on update data in database using codeigniter

<button id="survey_act" method="post" class="tiny ui blue button" type="button" value="<?php echo $surv['id']; ?>" >Activate Survey</button>
This is my button on click -
<script>
$(document).ready(function(){
$(document).on("click","#survey_act", function(){
alert(this.value);
idx = this.value;
$.ajax({
type: "POST",
url: "<?php echo base_url('index.php/admin/survey/act_surveyby_id/')?>/"+idx,
}).done(function(msg){
if(msg=="success"){
alert('You Successfully Activated the Survey!');
}
});
});
});
</script>
This is my javascript -
public function act_surveyby_id($id){
$this->load->model('survey_m');
if($this->survey_m->insert_activate($id)){
echo "success";
}else{
echo "invalid";
}
}
This is my controller -
public function insert_activate($id){
$date = date('m-d-Y',now());
$stat = 'Active';
$data = array(
'issued_date' => $date ,
'status' => $stat
);
$this->db->update('survey', $data)->where('survey_id', $id);
if($this->db->affected_rows()>0){
return true;
}else{
return false;
}
}
}
This is my model -
Problem: when i click the activate survey it wont change/update the details of the survey. I really badly need a help regarding with this. Thanks . . .

change $.ajax function like below
$.ajax({
url: '<?php echo base_url(); ?>index.php/admin/survey/act_surveyby_id',
type: "POST",
data: {
idx : idx;
},
and controller like below
public function act_surveyby_id(){
$id=$_POST['idx'];
$this->load->model('survey_m');
if($this->survey_m->insert_activate($id))
{
echo "success";
}else{
echo "invalid";
}

<input> calling a PHP function using AJAX

I am trying to call a PHP function using AJAX to check if the pressed button is the right button.
But I can't seem to figure it out.
I am using this as <input> code :
<?php
$i=0;
while ($i<4){
?>
<input style="background-color: <?php echo $buttonColors[$i]; ?>" onclick="echoHello(<?php echo $i?>)" type="submit" value="<?php echo $buttonName[$i]; ?>">
<?php $i=$i+1; } ?>
and I'm trying to call a PHP function when the button is clicked. I tried this :
<script>
function echoHello()
{
alert("<?php hello(); ?>");
}
</script>
<?php
function hello() {
echo "Hello World";
}
?>
This worked so I tried to change this to :
<script>
function echoHello(num)
{
alert("<?php hello(num); ?>");
}
</script>
<?php
function hello($num) {
if($num == 1) {
echo "Correct button!!!";
} else {
echo "WRONG BUTTON";
}
?>
But this didn't seem to work. What am I doing wrong?

I think you have quite some thing mixed up here.
I would suggest just writing out the buttons, and pass the buttons value to the javascript:
<?php
$i=0;
while ($i<4){
?>
<input onclick="echoHello(this.value)" type="submit" value="<?php echo $buttonName[$i]; ?>">
<?php
$i=$i+1;
} ?>
and then in your javascript (after adding all the jQuery goodness):
function echoHello(btnValue) {
$.ajax({
type: "POST",
url: "formhandler.php",
data: { buttonValue: btnValue }
})
.done(function( msg ) {
alert( "Data Saved: " + msg );
});
}
The javascript above will send the button value to your 'formhandler.php' page, using AJAX.
In the 'formhandler.php', you could then check what the value of $_POST["buttonValue"] is.
Using your setup, together with jQuery, PHP and JSON, it could be something like this:
function echoHello(btnValue) {
$.getJSON('page.php', {
choice: btnValue
})
.done(function(data) {
// based on $_GET["choice"], your PHP could render some JSON like:
// {"background":"image.jpg","fields":["newValue1", "newValue2", "newValue3"]}
// clear the current html
$("#form").html('');
// load a new background
$('body').css({'background-image':data.background})
// set up the new fields:
$.each(data.fields, function( i, item ) {
$("#form").append('<input type="text" value="' + item + '"/>');
});
});
}
This is just a sample, to give you an idea! It's untested also ;)
