I have the MYSQL part figured out but I cannot figure out how to properly display it. I have the following code and I made a select screen just to test: index.html <html> <body> <form action="select.php" method="post"> <input type="radio" name="table" value="table1"> Table 1 <br> <br> <input type="radio" name="table" value="table2">Table 2 <br> <br> <input type="radio" name="table" value="table3">Table 3 <br> <br> <input type="radio" name="table" value="table4">Table 4 <br> <br> <input type="radio" name="table" value="table5">Table 5 <br> <br> <input type="Submit" Name = "submit" value="Submit"> <input type="Reset" value="Reset"> </form> </body></html> select.php <?PHP $selected_radio = $_POST["table"]; if ($selected_radio = = 'table1) { echo "Table 1 Here."; } else if ($selected_radio = = 'table2') { echo "Table 2 Here."; } else if ($selected_radio = = 'table3') { echo "Table 3 Here."; } else if ($selected_radio = = 'table4') { echo "Table 4 Here."; } else if ($selected_radio = = 'table5') { echo "Table 5 Here."; } ?> These are two separate files. When I go to run the code, no matter what I pick, the next page is always blank. Again, the select.php is just suppose to be a check, the real code will display the table instead of echoing a message. Hi, I have 2 radio button's within a table and need to pass this array. All other rows within my table can be sent as array's and captured using $_POST['field_name'][$ROW 1 value etc]. However for radio buttons this doesn't work. As an example, a standard textbox I can send an array using the following: echo "<td width='33%'><input type='Textbox' width='100%' id='test' name='test[]' value='" .$row['test']. "'></td>"; I can then capture it using: $test = $_POST['test'][$iLine]; This works, no problem, however for radio buttons, I can't use a static array name, as presumably it dumps all rows into the array, if I do this, only the last row has a checked button, hence I need to use the following (where $checked includes the logic to decide whether the button should be checked or not, this works correctly): echo "<input type='radio' name='".$row['venue_id']."[]' value='1'".$checked."/>P1" echo "<input type='radio' name='".$row['venue_id']."[]' value='0'".$checked2." />P2"; I tried using the following: var_dump($_POST[$row]['game_id'][$iLine]); But this just returns a null value. Any ideas? Good Day, I juz like to know if there any other alternative way for the code below, coz i can't update my form when i use this method for radio the button. It's not passing the value. Code: [Select] Edit.php <tr> <td height="36" align="center" valign="middle" bgcolor="#990000"><div align="left" class="style4">Destroy :</div></td> <td align="center" valign="middle" bgcolor="#990000"><div align="left"> <label> <input type=radio name=destroyR value="Yes" <?php echo ($rows['destroy']=='Yes') ?'checked="checked"':''; ?> />Yes</label> <label> <input type=radio name=destroyR value="No" <?php echo ($rows['destroy']=='No') ?'checked="checked"':''; ?> />No</span></label> </div></td> </tr> how do you make it so that a radio button is either checked or unchecked based on database? I have a group of 4 radio buttons. my mysql database knows which one the user selected previously when they stored some information. I now wish to display the same buttons but have radio button checked that the user chose before. I know this can be done but having one of those mind melt moments where I cannot think of the solution so I have 4 buttons that look like this Code: [Select] <input type="radio" name="clarity" id="clarity" value="Opaque"> Opaque<br> <input type="radio" name="clarity" id="clarity" value="Deep"> Deep<br> <input type="radio" name="clarity" id="clarity" value="Mid"> Mid<br> <input type="radio" name="clarity" id="clarity" value="Pale"> Pale<br></td> I just need to attached a checked field to the correct item This topic has been moved to JavaScript Help. http://www.phpfreaks.com/forums/index.php?topic=346803.0 When I display the data in my database I have included a radio button in each row.

I am a complete newbie to PHP so please bear with me.. What I'm trying to do is to write a program that will go on to calculate a user's Body Mass Index (BMI) based on user inputted data of height and weight. However, I want to be able to accept heights and weights in a number of different units for maximum ease of use. I am trying to write some PHP code that will handle this , the main goal is to convert everything into 'cm' and 'kg' before going on and doing the simple BMI calculation later on. However I am stuck at this point: I have a text field for users to input their weight into. This is immediately followed by two radio buttons for the user to select which units they are inputting their weight in (kilograms or pounds). A third option to input their weight is given after this for those wishing to input their weight in 'stones and pounds'. My problem is as follows: I can't get my code to recognise which radio button (either 'kg' or 'lbs') has been pressed. What should happen is that my code can tell something has been inputted in the text box AND which of the radio buttons has been selected. From this it does one of the two; for the kilogram option it leaves the value as it is, but if the weight has been inputted in pounds (and the 'lbs' radio button selected) then I want the code to convert this into kilos by multiplying by 0.4535. Here is what I have so far (sorry its a bit messy - like i say I am a newbie): <?php //convert.php $ft = $cm = $inches = $weight = $stones =$pounds = $kilos = $units = ""; if(isset($_POST['cm'])) $cm = sanitizeString($_POST['cm']); if(isset($_POST['ft'])) $ft = sanitizeString($_POST['ft']); if(isset($_POST['inches'])) $inches = sanitizeString($_POST['inches']); if(isset($_POST['weight'])) $weight = sanitizeString($_POST['weight']); if(isset($_POST['stones'])) $stones = sanitizeString($_POST['stones']); if(isset($_POST['pounds'])) $pounds = sanitizeString($_POST['pounds']); if(isset($_POST['kilos'])) $kilos = sanitizeString($_POST['kilos']); if(isset($_POST['units'])) $units = sanitizeString($_POST['units']); if ($ft != '') { $height = intval(($ft * 30.48) + ($inches * 2.54)); $out = "you are $height cm tall"; } elseif($cm != '') { $height = intval($cm); $out = "you are $height cm tall"; } else $out = ""; if ($stones != '') { $kilos = intval((($stones * 14) + $pounds) * 0.45359237); $out2 = "you weigh $kilos Kg"; } elseif($weight != '' AND $units = "kg") { $kilos = $weight; $out2 = "you weigh $kilos Kg"; } elseif($weight != '' AND $units = "lbs") { $kilos = ($weight * 0.45359237); $out2 = "you weigh $kilos Kg"; } else $out2 = ""; echo <<<_END <html><head><title>Height & Weight Converter</title> </head><body><pre> Please enter your details below <b>$out$out2</b> <form method="post" action="convert.php"> Height: <input type="text" name="cm" size="3"> cm OR <input type="text" name="ft" size="1">ft <input type="text" name="inches" size="2">inches Weight: <input type="text" name="weight" size="4" /> Kg<input type="radio" name="units" value="kg" /> lbs<input type="radio" name="units" value="lbs" /> OR <input type="text" name="stones" size="2">stone <input type="text" name="pounds" size="2">pounds <input type="submit" value="Submit" /> </form></pre></body></html> _END; function sanitizeString($var) { $var = stripslashes($var); $var = htmlentities($var); $var = strip_tags($var); return $var; } ?> I am having some difficulty with accessing radio button values with PHP code.
