Are you using a database to populate the checkbox/input fields?

Member Avatar for ehpratah

Hi No im not using db. the intended process of that is when you check the checkbox the textbox will be shown and the user will input a value which is easy. but the tricky part for me is just to show only the selected checkbox on the preview page without the others

OK. I've had forms like this in the past and have wondered "do I really need the checkbox?" if the user enters a value in the text box would this be enough to say that they have selected "Gas: 200" ?

Does you page use JavaScript to add a text field if a checkbox is checked?

Member Avatar for EvolutionFallen

I have to agree with paulkd, are the checkboxes really necessary? Can't you just check if the value in the input box is not empty, and greater than 0?

Also, please provide your HTML and form processing code so we can see where you're having a problem.

This will show/hide the textboxes when clicking the checkboxes. (seems to have an issue with IE though)

<head>
    <style type="text/css">
        .tb_hide{display:none;}
    </style>

    <script type="text/javascript">
        function myfunction(id){
            e = document.getElementById(id);
            tb = document.getElementById(id+"_tb");
            if(e.checked){
                tb.style.display = "inline";
            }else{
                tb.style.display = "none";
            }
        }
    </script>

</head>

<form>
    <input type="checkbox" onchange="myfunction('gas_cb')"  name="gas_cb"  id="gas_cb"  value="Gas">Gas
    <input type="textbox" class="tb_hide" name="gas_cb_tb" id="gas_cb_tb"><br/>

hi do you mean something like this?

in my process form i'll make an if statement something like

$gas=$POST['Fuel'];

if($gas!=0){
echo"Gas:$gas";
}
else{

}

well haven't tested it yet but i thing this will work..thanks for the idea guys

Member Avatar for paulkd

This code is just a simulation of your code to show how you can code the form handler process.php. I have ommitted some text boxes in my form.

form

<form action="preview.php" method="post">
<p><input type="checkbox" name="ch-gas" value="Gas"> Gas <input type="text" name="gas" value="200"></p>
<p><input type="checkbox" name="ch-toll" value="Toll Fee"> Toll Fee </p>
<p><input type="checkbox" name="ch-gps" value="GPS"> GPS <input type="text" name="gps" value="200"></p>
<p><input type="checkbox" name="ch-lostkey" value="Lost Key"> Lost Key</p>
<p><input type="checkbox" name="ch-parkingfee" value="Parking Fee"> Parking Fee <input type="text" name="parkingfee" value="200"></p>
<input type="submit" value="Preview">
</form>

process.php

<?php 
foreach($_POST as $field => $value) {
    preg_match('/^ch\-([a-z]+)$/', $field, $matches);
    if($matches) {
        if($_POST[$matches[1]]!="") {
            echo $_POST[$field].': '.$_POST[$matches[1]].'<br>';
        }
    }
}
?>
