I need help only passing user input

[dj262501]

I appreciate your help guys. I was able to do something to the code. Now it looks like this:

 

<?php
include "include/dbc.php";

include "include/header.inc";
?>

<script type="text/javascript">
<!--Hide Code
// Function Statements

//Function to confirm submit

function confirmSubmit() {
var submitform = window.confirm("Are you sure you want to submit the activities?");
if (submitform == true)
	return validateForm();
return false;
}
// End Hide-->
</script>

<style type="text/css">
.mydate{
color:#00F;
text-decoration:underline;
cursor:pointer;
}
</style>

<script type="text/javascript">
function displayDate(d){
var date=new Date();
var D=date.getDate();
date.setDate(D+d);
var YYYY=date.getFullYear();
var MM=date.getMonth()+1;
MM<10?MM='0'+MM:null;
var DD=date.getDate();
DD<10?DD='0'+DD:null;
var span=document.getElementById('date');
span.innerHTML= 'Entries for '+MM+'/'+DD+'/'+YYYY;
}
onload=function(){displayDate(0)};
</script>

<h1>Food Diary</h1>

<div class="full">
<center><div><span class="mydate" onclick="displayDate(-1)"><img src="images/left_arrow.png" border="0">Yesterday</span>      <span id="date" style="font-size:2em;"></span>      <span class="mydate" onclick="displayDate(1)">Tomorrow<img src="images/right_arrow.png" border="0"></span></div><br />
<a href="#" onclick="displayDate(0);return false;">Today</a>
</center>

<div class="full">
<form name="exercise" id="exercise" method="GET" action="">
  <center><table>
<tr>
    	<td><h3>Add an Activity</h3></td>
</tr>
<tr>
    	<td><input name="NewSearchString" style="width: 100px" type="text"/>  <input type="submit" value="Search" /> </td>
</tr>
    <tr>
    	<td>

		</select>   <input type="submit" value="Submit" /></td></tr></table></center></form>
	</td>
</tr>
</table> </center>
<table width="100%">
   	<tr bgcolor="#66CC33">
    	<td><div>Activity</div></td>
        <td><div>Specific Activity</div></td>
        <td><div>Time (hh:mm)</div></td>
        <td><div>Distance</div></td>
        <td><div>Units</div></td>

    <tr bgcolor="#66CC33">

<?php
if(isset($_GET[activity])) {
$category=$_GET[activity];
$result = mysql_query("SELECT * FROM exercise WHERE type='$category'");
?>
<form action="add_activity.php" method="POST">
<?php
while($row = mysql_fetch_array($result)) {
echo '<tr><td><div>'.$row[Type].'</div></td>';
echo '<td><div>'.$row[Name].'<input type="hidden" name="exerciseid" value="'.$row[Name].'"></div></td>';
echo '<td><div><input type="text" name="duration['.$row['Name'].']"></div></td>';
echo '<td><div><input type="text" name="distance['.$row['Name'].']"></div></td>';
echo '<td><div><select>
        		<option value="mile" name="mile">mile</option>
            	<option value="Km" name="Km">km</option>
            	<option value="M" name="M">m</option>
            	<option value="Yard" name="yard">yrd</option>
            	<option value="Feet" name="feet">ft</option>
            </select></div></td></tr>';

}
mysql_close();
?>
<tr><td colspan="6" align="center"><input type="submit" name="submit" value="Add Activities"></td></tr>
</form>
<?php
}
?>
    <tr bgcolor="#66CC33">
    	<td><div></div></td>
     	<td><div></div></td>
       <td><div></div></td>
        <td><div class="Float"></div></td>
        <td class="cp_Distance"><div></div></td>
</tr></table>      

 

This somewhat works. The problem is that this code passes all the activities to the second page, where the output looks like this:

 

Array
(
    [exerciseid] => Hunting, general
    [duration] => Array
        (
            [Fishing from boat, sitting] => 20
            [Fishing from river bank, standing] => 
            [Fishing in stream, in waders] => 
            [Fishing, general] => 
            [Fishing, ice, sitting] => 
            [Hunting, general] => 
        )

    [distance] => Array
        (
            [Fishing from boat, sitting] => 25
            [Fishing from river bank, standing] => 
            [Fishing in stream, in waders] => 
            [Fishing, general] => 
            [Fishing, ice, sitting] => 
            [Hunting, general] => 
        )

    [submit] => Add Activities
)

 

Is there a way I can pass what the user input instead of passing everything (form validation maybe?)

The browser automatically passes every input whether or not it's empty. Trying to use JavaScript to create a work-around is a bad idea, as not everybody has JS enabled. That and it's much more hassle than it's worth, why not just check if the user entered anything with the PHP empty function?

You might want to work on defining what it is you want to do at each step.

 

You are currently displaying everything that your first form matches in one single form to all be submitted at once.

 

You might want to either output each activity as its' own form so that only one set of data gets submitted or if you want to be able to submit multiple sets of data, add a check-box form element to each set of data that you click. Your form processing code would then check if the check-boxes are set and only process the sets of data for checked boxes.

So you're saying instead of having multiple textboxes, I should replace them with checkboxes? What would be the best way to validate the form if I do it this way?
