I need help passing array variables/ singling out user data

[dj262501]

Hello all,

 

I'm hoping someone can help me out. Here is the code I have for a page that contains a user form:

 

 

<?phpinclude "include/dbc.php";include "include/header.inc";?><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 name="activity">            	<option value="_">Activity Browse...</option>                <option value="all">All Activities</option>                <option value="biking">Biking</option>                <option value="condition">Conditioning</option>                <option value="dancing">Dancing</option>                <option value="fish">Fishing & Hunting</option>                <option value="Home">Home Activities</option>                <option value="misc">Miscellaneous</option>                <option value="music">Music Playing</option>                <option value="occupation">Occupation</option>                <option value="running">Running</option>                <option value="sports">Sports</option>                <option value="walking">Walking</option>                <option value="water">Water Activities</option>                <option value="winter">Winter Activities</option>		</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>    <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><?phpif(isset($_GET[activity])) {$category=$_GET[activity];$result = mysql_query("SELECT * FROM exercise WHERE type='$category'");?><form action="add_activity.php" method="POST"><?phpwhile($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 name="metric[]">        		<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" onClick="return confirm(  'Are you sure you want to submit the 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>      

 

 

 

And here is the page that the user information is supposed to be passed to:

 

 

<?phpinclude "include/dbc.php";include "include/header.inc";$duration = $_POST["duration['.$row['Name'].']"];echo '<h1>Added Activities</h1>';echo $duration;?>

 

 

Well, this isn't working for me. The second page code returns this error:

 

 

Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING

 

 

When I execute print_r, the values are returned to me. So I have two questions:

 

1) What do I need to do to change the code on the 2nd page to echo and POST the array?

 

2)The database contains multiple exercises under the same name. So, when the variables are passed to the 2nd page. All the values are returned regardless of whether they have been filled out or not. What can be done to only returned the user input and not the blank variables?

Should be:

 

 

$duration = $_POST["duration['".$row['Name']."']"];
