bro,

unsa may buhaton ani nga function ? $sampleclass->display()
ang return value ana ang gusto nimo ipa display?

**tynum** · 02-15-2009, 04:39 PM

ang problema nku ani bro kay dili kung unsay buhaton sa function.... kundi pag invoke sa function....
kay dili mu run ang PHP na function pag invoke nku sulud sa javascript...

na instantiate na nimo ang $sampleclass na object?

**tynum** · 02-15-2009, 11:06 PM

naa na ko'y improvements mga bro....
ako ra gbalhin ang script tag sa ubos sa mga PHP statements nku...

<?php
$begin = new sampleclass(); //instantiating class
.
// codes here
.
?>
<input type="image" src="https://www.istorya.net/forums/images/confirm.png" name="confirmButton" onClick= test()></input>
<script type="text/javascript">
function test()
{
var result=confirm('Are you sure to continue Mr.<?php echo $name; ?>');
if( result == true)
{
<?php $begin->save(); ?> // save() do insert query to DB
}
</script>

ang problem nsad ani kay mu diretsu xa ug buhat sa statement na $begin-save() bsag wala pa nku ma click ang confirmButton which has an onClick attribute... nkahibaw ko na ni run ug una ang statement na $begin-save() kay nka insert man xa sa ako DB...

ang gusto ra jd unta nku ani kay:

-mugawas ang confirm window if gusto ba niya e save or not
-if yes, do query via $begin->save()

so far wala pa nku nakuha ang gusto nku makuha.... tabang.... nkasabot mo sa ako prob?
possible ba ni?

You lack a closing curly brace. I don't think na pwede na sa javascript? I'm a beginner pa man sad.

Here is how I would do it:

Code:

<html>
<head>
  <title>Mic Test</title>
</head>
<body>
<?php
$sample = new Sample();

if(!$_POST) {
  echo 'Do you want to continue ' . $name . '?'; 
  
  ?>
  <form method="post">
  <input type="checkbox" value="1" name="answer" />
  <input type="submit" name="Submit" />

<?php
}
else {
  if(isset($_POST['answer']) && $_POST['answer']) {
    $sample->save();
  } else {
    echo 'Okay...';
  }
}
?>
</body>
</html>

http is stateless. you have to get used to not treating a website or page like a desktop app. once you have served an html page you "lose" connection to the PHP objects. these days there's ajax but that's another story.

Code:

<script>
function test() {
    var msg = '...';
    if (window.confirm(msg))
        window.location.href = '/url/to/db/save';
}
</script>

keep in mind that php is server side while javascript is client side.

so basically php runs, even before the page is returned from a request.

maybe you can try this one.

<html>
<head>

<?php
//just a sample functions
function sampSAVEfunc(){

echo "document.writeln('Save Code Exceuted<br>')";

}

?>

<script type="text/javascript">

function checkentry(){
<?php $name='edvincent'; ?>

var res = confirm('Would you like to continue Mr. <?php echo $name; ?>');
return res;

}

<?php if($_POST['buttontext']){ sampSAVEfunc(); ?>

document.writeln("success");

<?php } ?>

</script>
</head>
<BODY>

<form name="frm" method="post" action="<?php echo $_SERVER['REQUEST_URI']; ?>">
<input type = "submit" name="buttontext" value="Click here" onclick="var stat=checkentry();return stat;">
</form>

</BODY>
</html>
