forms with php

[pugs1501]

I am creating a form in PHP and I can get most of it to work. I am just having problems with the check box feature. I want to be able to have a check box that the user will select multiple items and then put them all into one variable so when I do a Mysql call looking for one of the items it will show me that user chose it. Here is just a test form I am just trying to get the Functionality working.

 

<?php

if ($_GET['catupdate'] == 'Update'){

 

$pets1 = $_GET[pets]." ".$_GET[pets]." ".$_GET[pets];

echo $_GET['catname'];

echo "<br>\n";

echo $_GET['catrank'];

echo "<br>\n";

echo $_GET['catint'];

echo "<br>\n";

echo $pets1;

 

}else{

echo "<center><table border=0 cellpadding=0 cellspacing=0 width=90%>";

echo "<form method=get action=index.php>";

echo "<tr><td><font color=000000>Name: </font><input type=Text size=40 name=catname></td></tr>";

echo "<tr><td><font color=000000>Rank: </font><input type=Text size=40 name=catrank></td></tr>";

echo "<tr><td><font color=000000>Initial: </font><input type=Text size=15 name=catint></td></tr>";

echo "<tr><td><font color=000000>pets: </font><input type=checkbox name=pets value=dog> dog</td></tr>";

echo "<tr><td><font color=000000>pets: </font><input type=checkbox name=pets value=cat> cat</td></tr>";

echo "<tr><td><font color=000000>pets: </font><input type=checkbox name=pets value=rat> rat</td></tr>";

echo "<tr><td><center><input type=Submit name=catupdate value=Update></center></td></tr>";

echo "</form></table></center>";

 

}

 

?>

 

 

here is what the result looks like

 

testdata    // catname variable

2              // catrank variable

example    // catint Variable

rat rat rat  // pets variable with a space

 

 

I would just make the name of the check boxes all different but when I am pulling from a database for the selections I am not sure how many I would have. Any help would be very much appreciated.

um, well firstly use"

 

name = 'value'  instead of:

name=value

 

in terms of your database.

 

simply loop through the result and echo out relevent values to checkboxes.

If you want to get multiple values back from a checkbox, you need to make the name an array. Also you should always quote all values of all attributes.

 

<?php
   echo "<form method='get' action='index.php'>";
   echo "<tr><td><font color='000000'>Name: </font><input type='Text' size='40' name='catname'></td></tr>";
   echo "<tr><td><font color='000000'>Rank: </font><input type='Text' size='40' name='catrank'></td></tr>";
   echo "<tr><td><font color='000000'>Initial: </font><input type='Text' size='15' name='catint'></td></tr>";
   echo "<tr><td><font color='000000'>pets: </font><input type='checkbox' name='pets[]' value='dog'> dog</td></tr>";
   echo "<tr><td><font color='000000'>pets: </font><input type='checkbox' name='pets[]' value='cat'> cat</td></tr>";
   echo "<tr><td><font color='000000'>pets: </font><input type='checkbox' name='pets[]' value='rat'> rat</td></tr>";
   echo "<tr><td><center><input type='Submit' name='catupdate' value='Update'></center></td></tr>";
?>

 

Then in your processing, you would do:

<?php
f ($_GET['catupdate'] == 'Update'){
   
   $pets1 = implode(' ',$_GET['pets]');
   echo $_GET['catname'];
   echo "<br>";
   echo $_GET['catrank'];
   echo "<br>";
   echo $_GET['catint'];
   echo "<br>";
   echo $pets1;
?>
