i have a php variable that holds a date and i want to pass to a javascript function, but what happens is that i get a junk value instead, what should i do?

$data = $_POST['datep'];
echo "<script language=javascript>fnClickAddRow($nplaca,$defeito,$posicao,$data);/script>";
<script type="text/javascript">
function fnClickAddRow(n__placa,defeito2,posicao2,dataf) {
	var lext = "<?php echo $l_ext ; ?>";
        $('#table1').dataTable().fnAddData( [	                              	
		                                 	lext,                                 	
		                                 	n__placa,
		                                 	defeito2,
		                                 	posicao2,
		                                 	dataf		                                 	
	]);
	}
</script>

everything except dataf prints fine on the table (datatables).

the $l_ext wasnt working either until i found this solution (echoing to the var), but doing the same for dataf doesnt work ($l_ext is GET instead of POST)

if i echo the $data on php (before calling the javascript function) i can see the date on the format i want (dd/mm/yyyy) but after it passes to javascript i can see only a string of numbers (0.00048958943893).


thanks

Drako12,

Try it like this ...

<script type="text/javascript">
var nplaca = <?php echo $nplaca; ?>
var defeito = <?php $defeito; ?>
var posicao = <?php $posicao; ?>
var data = <?php $_POST['datep'] ?>
fnClickAddRow(nplaca,defeito,posicao,data);
</script>

If it still gives trouble then use your browser's "view source" to see what is actually in the served page.

i didnt understand where/how i should use this code, maybe i explained my problem poorly.

the first part is on a PHP code where i get some values into variables after a submit and i call a javascript function with those variables into it.

$posicao = $_POST["posicao2"];
$defeito = $_POST["defeito2"];
$nplaca = $_POST["n_placa"];
$data = $_POST['datep'];

echo "<script language=javascript>fnClickAddRow($nplaca,$defeito,$posicao,$data);</script>";

the second part is the actual javascript code, which has jquery functions to add a row to a table (datatables)

<script type="text/javascript">
function fnClickAddRow(n__placa,defeito2,posicao2,dataf) {
	var lext = "<?php echo $l_ext ; ?>";
    $('#table1').dataTable().fnAddData( [	                              	
		                                 	lext,                                 	
		                                 	n__placa,
		                                 	defeito2,
		                                 	posicao2,
		                                 	dataf	                                 	
	]);
	}
</script>

the problem im seeing is that the PHP variable $data holds a date in a format dd/mm/yyyy and when its passed to the javascript function it turns into a float number (ie: 0.00003459874353897).


thanks for the help

i just tested something, nothing other than integers can be passed, if i try to pass a text on the input i get XX (being the value) is not defined.

why is that?

solved the problem, the PHP variable has to be inside single quotes to be passed as a text otherwise it will convert into a number.

That's because text values must be in singel or double quotes.

Going back to my earlier suggeston and assuming all the values to be text :

<script type="text/javascript">
var nplaca = "<?php echo $_POST["n_placa"]; ?>"
var defeito = "<?php $_POST["defeito2"]; ?>"
var posicao = "<?php $_POST["posicao2"]; ?>"
var data = "<?php $_POST['datep'] ?>"
fnClickAddRow(nplaca,defeito,posicao,data);
</script>

Here, you are building javascript statements by inserting php values into HTML/javascript text-strean that forms the served page. All parts that are not inside <?php ... ?> delimiters are just hard-coded javascript in the same way you use php to build HTML.

If any of the values is not text then simply remove the quotes.

OK, you got there moments before me. Well done
