how to save html to variable?

I try to save wysiwyg data to a variable but I keep getting a error message
"Uncaught SyntaxError: Unexpected token ILLEGAL"
And I cant get my head around it... I can se in the console that everything
is retrieved ok, anyone with an idea of what could be the error.
javascript
var temp = "<?php echo $pressDescription ?>"
console

You have to escape characters which have special meaning or are not allowed in JavaScript string literals (such as new lines).
The json_encode function will do that for you.
var temp = <?php echo json_encode($pressDescription); ?>;

Just use escape characters. For example:
var varName1 = '<p class="className">Sample text</p>';
var varName2 = '<p class=\'className\'>Sample text</p>';
var varName3 = "<p class=\"className\">Sample text</p>";

JavaScript - Bring multiple variables from PHP

I have the following PHP code. It creates multiple variables using $a; for example: $numtoken1.
$sql ="SELECT token, dispositivo FROM dispositivos WHERE idcliente=1";
mysql_select_db('localiza');
$retval = mysql_query( $sql, $conn );
$num_rows = mysql_num_rows($retval);
while($row = mysql_fetch_array($retval, MYSQL_BOTH))
{
$numtoken['$a']=$row['token'];
$numdispositivo['$a']=$row['dispositivo'];
$a=$a++;
}
Using JavaScript, I want to call all the PHP variables using that code, but it only get the last $a number.
My question is: In a JavaScript loop, how can I dynamically insert the value for $a? Because in the above PHP, I have multiple values for $a.
var accessToken = "<?= $numtoken['$a']; ?>"a;
var deviceID = "<?= $numdispositivo['$a']; ?>";

I suggest JSON:
var accesstoken = JSON.parse("<?= json_encode($numtoken); ?>");
var deviceID = JSON.parse("<?= json_encode($numdispositivo); ?>");

So the first thing I noticed when looking at this is that you are wrapping $a in single quotes (') instead of double quotes (") this means that instead of evaluating $a the key in the array will be the string "$a", so you'll be overwriting the value in each iteration of the while loop. See - http://php.net/manual/en/language.types.string.php#language.types.string.parsing for more info.
That being said the actual answer to your question varies, but the simplest method might be to use the json_encode function to convert your arrays into json objects.
var accessTokenArr = <?php print json_encode($numtoken); ?>
var deviceIdArr = <?php print json_encode($numdispositivo); ?>
Then you can iterate over the values in those arrays and do whatever you want to with the values. Fair warning - you may need to tweak that code a little as I haven't tested it to make sure it plays nicely.

passing php string of JSON ( with qoutes) to onclick function

I'm trying to pass an array of data from php to java script for "onclick" event.
I do it by converting the array data into JSON string in order to parse it back in the js function and work on it.
The problem is that JSON string contains double quotes , so it arises an error as the double quotes break the html string (Uncaught SyntaxError: Unexpected token ILLEGAL ). I did see several questions similar to this, but didn't find a solution to what I need, or maybe I didn't understood the correct solution. So I bring it up here with my specific case.
<?php
..some php code here..
$aData = array("You","Me",76,array(3,6));
$sJSONstr = json_encode($aData);
?>
<input type="button" name="formSubmit" value="Delete" onclick="analyze('<?php echo $sJSONstr; ?>')">
<?php
..some php code here..
?>
and the js function is as follows:
function analyze(i_sInputDataJSONStr)
{
var aInputData = JSON.parse(i_sInputDataJSONStr);
.. So something with the input data array..
}

Use single quotes for the onclick attributes instead of double quotes. Single quotes is equally valid as double quotes.
One more thing, since you already have your data in JSON format, there is no need to put it as a string in the analyze function call, since your JSON data is a valid JavaScript array (that's what JSON stands for: JavaScript Object Notation).
Therefore, you don't have to parse the input string in your analyze function declaration.
Consider the following example, this is perfectly valid code.
<?php
$arr = ["Hello", "World"];
$json = json_encode($arr); // $json = '["Hello","World"]'
?>
<div id="myDiv" onclick='doSomething(<?php echo $json; ?>)'>Click me</div>
<script type="text/javascript">
function doSomething(data){
for (var i = 0; i < data.length; i++) {
alert(data[i]);
}
}
</script>

create a javascript string and pass it:
<script type="text/javascript">
var myjson = '<?php echo $sJSONstr; ?>';
</script>
and then:
onclick="analyze(myjson)"

<input type="button" name="formSubmit" value="Delete" onclick='analyze(<?php echo $sJSONstr?>)'>
Replace the double quotes with single quotes in onclick='';
Worked like a charm for me.

Add a comma to the end of each line using php [duplicate]

This question already has answers here:
Convert php array to Javascript
(21 answers)
Closed 9 months ago.
I am having a csv file with 1 email id in each line. I want to add comma after each email id. I want to add a comma to the end of each line using php. How can i do this? Is there a particular function for that?
UPDATE
I want this so that I can construct an array out of it in javascript.
I will be loading the csv file using php and then printing it in my js.
Like
var myCars=[<?php print $csv; ?>];
So that I acheive something like this.
var myCars=["Saab#gmail.com","Volvo#gmail.com","BMW#gmail.com"];
Or is there a better way to do this?

$lines = file('file.csv');
foreach ( $lines as & $line ) {
$line .= ',';
}
file_put_contents('file.new.csv', implode(PHP_EOL, $lines));
something like that should do,
cheers

<?php
$lines = file('org.csv');
foreach ( $lines as & $line ) {
$line = trim( $line ) . ',';
}
file_put_contents('new.csv', implode(PHP_EOL, $lines));

Why not use the csv-specific functions?
$old = fopen('file.csv','r');
$new = fopen('new.csv','w+');
while($line = fgetcsv($old))
{
fputcsv($new,$line);
}
fclose($old);
fclose($new);
The above code will write a new csv, line per line, but if you just want to generate a javascript array, why not do this:
$file = fopen ('file.csv','r');
$all = array();
while($line = fgetcsv($file))
{
$all[] = $line[0];//if there is only 1 field/line
$all = array_merge($all,$line);//if multiple
}
fclose($file);
$js_array = '["'.implode('",',$all).'"];';
//or, the way I'd advise against, but good for multi-dimensional, assoc arrays
echo 'var array = JSON.parse("'.json_encode($all).'");';

why not just
$csv = str_replace("\n", ",\n", $csv);

Instead of echoing an entire csv string, you can import the file to an array using the fgetcsv function, then echo it out using json_encode(). That way you're sure to get a valid javascript array. It will also quote and encode any strings for you.
Oh, remember to run the array through some iterator which will run utf8_encode on all strings. If you have invalid utf8 characters, json_encode will barf.
There are plenty of examples on php.net of doing the different parts of this, but I can provide some examples if needed.

how to use jquery selectors in a for loop?

i want to acheive this :
for (i = <?php echo $current_i ?> /*then I get augmented in javascript */;i<max;i++){
$('#anyid****')./* my actions goes here */
}
here i want to put the counter I of the javascript in the selector
how could i do that ???

Sorry i don't know PHP but i hope you wanted to do something like below
for (i = <?php echo $current_i ?> ;i<max;i++){
$('#div'+i)/*do the rest*/
}
the + is for concatenation, i hope it is same in PHP. Also you could cast i to string.
Just for OP's understanding
in line 2 $('#div'+i) i is a integer type and others $(#div) are of type string. For jquery needs a string selector to retrieve a matching dom node and for that i needs to also be casted/converted to a string variable so that it could concatenate/add/attach with the prefix string which is in this example #div. in c# you add 2 strings like this var result = "#div" + i.ToString(); and i did not know PHP equivalent for + in c#,hence a sorry at the start of post. Now do you understand?

for (i = <?php echo $current_i ?> /*then I get augmented in javascript */;i<max;i++){
$('#anyid' + i)./* my actions goes here */
}
you can just concatenate it to the string of your selector.

That's not very "jQuery-ish". Assuming the elements have IDs with a continuing part and are in order, you can give every element a common class and use slice [docs] and each [docs]:
$('.commonClass').slice(<?php echo $current_i ?>, max + 1).each(...
You could provide better solutions if you explain more about your problem. E.g. giving each element an increasing ID does not seem to be a deliberate solution.
P.S.: I wouldn't put the PHP variable there either, maybe assign the value to a JavaScript variable first.

it would be a lot cleaner if you split up the php and javascript like this.
js_var.php
<?php
$phpvars = array(
'max' => 12,
'fop' => 22
);
function phpvar($key = NULL){
global $phpvars;
return ($key)
? json_encode($phpvars[$key])
: json_encode($phpvars);
}
?>
usage
<?php include('phpvars.php');?>
<script type="text/javascript">
window.phpvars = <?=phpvar()?>;
var max = phpvars.max;
for (var i=0;i<max;i++){
console.log(i);
}
console.log(php);
</script>
