i have a problem with php and javascript 😉
okay this is the scenario :

i have a textbox and a button on main page. when i press this button new window is popuped( child window).. which is a php page.. i

am not using method=send and action="xxx.php" coz i have to show this page in a pop up. so the value of textbox in parent window is

carried to child window (popup) by javascript : opener.document.formname.txtboxname.value and i need to set this value to some

variable in php for database query ... get the result and send back the result to the main window.

i tried to set the value carried from parent window to a hidden field on php page and set it's value to some variable ...by doing

something like this

<?php

print<<<EOF
<form name="xyz">
<input type="hidden" name ="abc"> //this is a hidden field
</form>
EOF;

echo'
// this sets the value from main window to hidden field ... it does sets the value
<script language = JavaScript>
document. xyz.abc.value = opener.form.txtbox.value;
</script>
';

$somevar = $abc
// this is not working ....
?>
... i just couldnt find a way to do this ...

does anyone know a better way to do this ??? please ENLIGHTEN me ... i am stucked at my work with this simple thingy .. help

meeee. you can mail me at ilam@gispl.com
hope i did make myself clear and you understood what i want 😉

you open the ne window, pass the value from the parent to the child window placing it in a hidden variable, and then you want that value to be used by a php script right?

well, ya gotta submit the form with the value via js to pass the value to the php script

<body onLoad="myfunction();">
<form name="xyz" action="$PHP_SELF" method=post>
<input type="hidden" name ="abc"> //this is a hidden field
</form>

thanks bastien,

that would have worked fine only if it didnt fell in contineous loop.. you know what i mean ?? 😉 it's coz of calling the funciton on <body onload="myfunction()"> which will trigger < ... action="PHP_SELF"> and which will again call myfunction() from onload .. this goes on and on and on ... heheheh ...

what do you say ?? is there any way to over come this .. and i need to call the function at onload() event ...

zlich (:

sorry about that

in your php page add a check to see if the var is set

if yes then execute the db code or whatever

if no then let the page get the values from the js

if (isset($_POST['abc'])){
//execute all other code
}else{
echo "<body onLoad="myfunction();">
<form name=\"xyz\" action="$PHP_SELF" method=post>
<input type=\"hidden\" name =\"abc\"> //this is a hidden field
</form>

obviously need to change this to make it correct but should give you the idea.
