dj262501 Posted September 23, 2010 Share Posted September 23, 2010 Hello all, I need your help. I have two pages. This is the 1st page: <?php include "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> <?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'].']" value=""></div></td>'; echo '<td><div><input type="text" name="distance['.$row['Name'].']" value ""></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> This page contains a table that is pulling info from a database stored in phpmyadmin. The values entered in that table are passed to the second page: <?php include "include/dbc.php"; include "include/header.inc"; $exerciseid = $_POST["exerciseid"]; $duration = $_POST["duration"]; $distance = $_POST["distance"]; $metric = $_POST["metric"]; echo'<h1>Added Activities</h1>'; // name of array echo '<h1>Exercise</h1>'; if (is_array($exerciseid)) { foreach ($exerciseid as $key => $value) { echo $key .' : '. $value .'<br />'; } } echo '<h1>Duration</h1>'; if ($duration == ""){ echo "No value"; } // name of array echo '<h1>Distance</h1>'; if (is_array($distance)) { foreach ($distance as $key => $value) { echo $key .' : '. $value .'<br />'; } } // name of array echo '<h1>Metric</h1>'; if (is_array($metric)) { foreach ($metric as $key => $value) { echo $key .' : '. $value .'<br />'; } } ?> The problem is that ALL the values, empty or w/content, are being passed. So I was wondering if there was a way to pass only user input with an if/else statement. Something like: if ($duration == ""){ echo "No value"; else echo duration; } This, however, is not working and I would like to know what possibly could work that would be structured similarly. Thanks in advance. Quote Link to comment Share on other sites More sharing options...

dj262501 Posted September 23, 2010 Author Share Posted September 23, 2010 if ( empty($duration) ) { echo "No value"; } else { echo $duration; } Thanks for the help, but for some reason it's coming back as array Quote Link to comment Share on other sites More sharing options...
Chris92 Posted September 23, 2010 Share Posted September 23, 2010 That would be because $duration is an array. Quote Link to comment Share on other sites More sharing options...
dj262501 Posted September 23, 2010 Author Share Posted September 23, 2010 That would be because $duration is an array. Is there anyway to return just user input and not blank vales/array? Quote Link to comment Share on other sites More sharing options...
Chris92 Posted September 23, 2010 Share Posted September 23, 2010 Proboably an easier way around.. but I'd do it like this: if( empty($duration) || count($duration) == 0 || $duration == "" ) { echo "fail"; } else { echo "AIGHT!"; } Quote Link to comment Share on other sites More sharing options...

Another question: Is there any way to just block empty values and not return anything? Right now I keep getting array Quote Link to comment Share on other sites More sharing options...
