I am trying to pass multiple variable using JavaScript and PHP, but not being able to do that.
echo "<a href=javascript:popcontact('btsdetails.php?uid=" . $row["bs_id_site"] . "&sid=" . substr($row['bs_id'], -1) . "')>" . $row['bs_id'] . "</a>";
Therefore, I am trying to POST "uid" and "sid" using & sign, but it is not working. It is only accepting the "uid".
Can anyone help me to solve this problem?
Here is the answer:
<script type="text/javascript">
function popcontact(uid, sid){
window.location = "btsdetails.php?uid="+uid+"&sid="+sid;
}
</script>
<?php echo $row['bs_id']; ?>
you can use http_build_query
<?php
$params = array("uid"=>$row["bs_id_site"], "sid"=>substr($row['bs_id'], -1));
$url = "btsdetails.php?".http_build_query($params);
?>
<?= $row['bs_id'] ?>

PHP CODE:
$video1="welcome.mp4";
$video2="movie.mp4";
$video3="ends.mp4";
$num_id="1";
$get = '$' . "video" . $num_id;
$file = $get;
echo "<a href=Player.php?file=$file'>Play</a>";
html code results:
Play
HTML - expectancy:
Play
I would do something like this.
$videos = ['welcome.mp4','movie.mp4','ends.mp4'];
foreach($videos as $video){
echo "<a href=Player.php?file=$video'>Play</a><br>";
}
I would do this (If I wanted to be Kool, or confuse a junior developer .. lol )
$video1="welcome.mp4";
$video2="movie.mp4";
$video3="ends.mp4";
$num_id="1";
$get = ${"video".$num_id};
$file = $get;
echo "<a href=Player.php?file=$file'>Play</a>";
Output
<a href=Player.php?file=welcome.mp4'>Play</a>
But I am not sure you are ready to have access to that much power...

This block of PHP code prints out some information from a file in the directory, but I want the information printed out by echo to be used inside the HTML below it. Any help how to do this? Am I even asking this question right? Thanks.
if(array_pop($words) == "fulltrajectory.xyz") {
$DIR = explode("/",htmlspecialchars($_GET["name"]));
$truncatedDIR = array_pop($DIR);
$truncatedDIR2 = ''.implode("/",$DIR);
$conffile = fopen("/var/www/scmods/fileviewer/".$truncatedDIR2."/conf.txt",'r');
$line = trim(fgets($conffile));
while(!feof($conffile)) {
$words = preg_split('/\s+/',$line);
if(strcmp($words[0],"FROZENATOMS") == 0) {
print_r($words);
$frozen = implode(",", array_slice(preg_split('/\s+/',$line), 1));
}
$line = trim(fgets($conffile));
}
echo $frozen . "<br>";
}
?>
The above code prints out some information using an echo. The information printed out in that echo I want in the HTML code below where it has $PRINTHERE. How do I get it to do that? Thanks.
$("#btns").html(Jmol.jmolButton(jmolApplet0, "select atomno=[$PRINTHERE]; halos on;", "frozen on")
You just need to make sure that your file is a php file..
Then you can use html tags with php scripts, no need to add it using JS.
It's as simple as this:
<div>
<?php echo $PRINTHERE; ?>
</div>
Do remember that PHP is server-side and JS is client-side. But if you really want to do that, you can pass a php variable like this:
<script>
var print = <?php echo $PRINTHERE; ?>;
$("#btns").html(Jmol.jmolButton(jmolApplet0, "select atomno="+print+"; halos on;", "frozen on"));
</script>
Basically what I have is, there is an index file, that links to a JS file, which then pulls in a PHP file.
So in the PHP file I have (along with other code) :
echo " <script type='text/javascript'>var paging = [ ";
echo "{";
echo "numrows:'" . number_format($numrows) . "',";
echo "pagenum:'" . number_format($pagenum) . "',";
echo "maxpage:'" . number_format($maxpage) . "',";
echo "record_min:'" . number_format($record_min) . "',";
echo "record_max:'" . number_format($record_max) . "'";
echo "}];</script>";
Then, in a JS file I use ajax:
req.open("GET", "server.php", true);
and within the readystatechange I need to retrieve that paging variable you see from the php file because it contains data from the database.
In the JS file I have tried using a variable instead of echo
var m=<?PHP echo $paging; ?>
but that doesn't work either.
Any suggestions or ideas how to get this to work?
I'd use JSON instead of JS. You should be able to pass a PHP array to the json_encode function. See: http://php.net/manual/en/function.json-encode.php
Also, on the PHP side, you may want to modify your response headers to indicate that the response message body is JSON:
header( 'Content-Type: application/json' );
Then, use jQuery to get the JSON from the server: http://api.jquery.com/jQuery.getJSON/
Another possible solution for you if you don't get direct JSON working (scaled down to two variables)
echo '<div id = "numrows">'. number_format($numrows) . '</div>';
echo '<div id = "pagenum">'. number_format($pagenum) . '</div>';
in the php file
req.onreadystatechange = function(){
if (req.readyState == 4 && req.status == 200){
document.getElementById('return').innerHTML = req.responseText;
}
}
req.open("GET", "server.php", true);
req.send();
n["numrows"] = document.getElementById("numrows").innerHTML;
e = document.getElementByID("numrows");
e.parentNode.removeChild(e);
n["pagenum"] = document.getElementById("pagenum").innerHTML;
e = document.getElementByID("pagenum");
e.parentNode.removeChild(e);
in the javascript
<div id = "return" style="display: none;"></div>
in the html
Not the most elegant solution, but fairly straightforward to follow if you can't get anything else working.
Ok because jQuery makes this easy, here is my example:
$paging = array(
"numrows" => number_format($numrows),
"pagenum" => number_format($pagenum),
"maxpage" => number_format($maxpage),
"record_min" => number_format($record_min),
"record_max" => number_format($record_max)
);
$output = json_encode($paging);
header( 'Content-Type: application/json' );
echo $output;
Then in your javascript page using jquery do this:
function myCallBackFunction(data){
alert(data.numrows);
}
$.getJSON('server.php',myCallBackFunction(data));
Hope this helps.
Edited to use array and json_encode
http://www.reecemcmillin.com/albums/
<?php
$uncut = file_get_contents('http://www.google.com/#sclient=psy-ab&hl=en&safe=active&source=hp&q=' . $_POST['band'] . '+' . $_POST['album'] . '+zip+inurl:mediafire');
$strip1 = strstr($uncut, 'www.mediafire.com/?');
$link = substr($strip1, 0, 30);
echo $link;
?>
It doesn't seem to be writing the website content to $uncut. Can somebody help me figure out what's wrong? Thanks.<3
Clients are not supposed to send URI-fragments (the portion of the URI following #) to servers when they retrieve a document. PHP is probably sending a request for the google homepage, effectively: file_get_contents('http://www.google.com/');. If you echo $uncut, that's probably what you'll see you're getting back.
Try a querystring-based URI instead.
<?php
$uncut = file_get_contents('http://www.google.com/search?sclient=psy-ab&hl=en&safe=active&source=hp&q=' . urlencode($_POST['band']) . '+' . urlencode($_POST['album']) . '+zip+inurl:mediafire');
I seem to have a syntax error and can't see it myself, could someone run over it for me please?
Thanks.
<script>
var acurl_<?php echo $request_data['friendship_id']; ?> = "sn-include/create_bond_accept.php?friendship_id=<?php echo $request_data['friendship_id']; ?>&friend_id=<?php echo $fromuser['id']; ?>";
</script>
Because you got some answers that intended to show you how to improve your code, but actually don't do so (IMO), here is my attempt:
<?php
$acurl = array();
$acurl[$request_data['friendship_id']] = sprintf('sn-include/create_bond_accept.php?friendship_id=%s&friend_id=%s', $request_data['friendship_id'], $fromuser['id']);
?>
<script>
var acurl = <?php echo json_encode($acurl); ?>
</script>
I would not create dynamic variable names. This code would create a JS object, where the properties are the friendship IDs, something like:
{
'42': 'sn-include/create_bond_accept...'
}
You can access these URLs more easily from JavaScript than if you have dynamic variable names.
David, on the bright side, you don't have a syntax error.
If you're developing PHP, I would recommend two things:
Get a better IDE. Dreamweaver is TERRIBLE for working with PHP. I recommend NetBeans (it's awesome and free).
Start breaking up your code into chunks. The big ball of html and PHP is hard to debug.
Check this out:
<?php
// prepare output
$segment = '?friendship_id=' . $request_data['friendship_id'];
$segment .= '&friend_id=' . $fromuser['id'] . '";' . "\n";
$acurl = 'var acurl_' . $request_data['friendship_id'];
$acurl .= ' = "sn-include/create_bond_accept.php';
$acurl .= $segment;
$dnurl = 'var dnurl_' . $request_data['friendship_id'];
$dnurl .= ' = "sn-include/create_bond_deny.php';
$dnurl .= $segment;
?>
<script type="text/javascript">
<?php
echo $acurl;
echo $dnurl;
?>
</script>
Use here doc instead:
<?php
echo <<<JS
<script>
var acurl_{$request_data['friendship_id']} = "sn-include/create_bond_accept.php?friendship_id={$request_data['friendship_id']}&friend_id={$fromuser['id']}";
</script>
<script>
var dnurl_{$request_data['friendship_id']} = "sn-include/create_bond_deny.php?friendship_id={$request_data['friendship_id']}&friend_id={$fromuser['id']}";
</script>
JS;
?>
