I have this whole code. Jumbled but what I'm trying to do is to have a drop down menu with selections from 1 -10. Then after selecting one, would spit out another form so that if there 3 were selected, would show three rows of fields (name, email). Validation included. What I was first "hard coded" on how many rows of fields to spit out but now what I wanted to do is to have a "selection" in dropdown menu so that the user has the ability to select.... Seem to work but doesn't process. Any PHP expert help? No db, no client-base, no smart alec. If you have time to help please do.

You have to move the second form submit code outside of first form submit. Try this

I am struggling to get my PHP unit converter to work.

It'd be great if someone could show me where I'm going wrong and help me get it going. :)

If you want to make a converter, all you need is one input - and a dropdown between what you wish to convert to. Then use a switch in PHP when the form was submitted to check what function you wish to use.
Your current issue is that you overwrite a lot of values, and that you don't check for the right buttons. This is also over-complicating it.
You can further develop this converter by making sure that the input is an actual number - by using filter_var() with a flag that's suitable for your need. You can either validate it or sanitize it, see FILTER_SANITIZE vs FILTER VALIDATE, whats the difference - and which to use?.
<?php
if (isset($_POST['submit'])) {
switch ($_POST['convert']) {
case "cm-in":
$result = centimeter_to_inches($_POST['value']);
$old_unit = 'cm';
$new_unit = ' inches';
break;
case "in-cm":
$result = inches_to_centimeter($_POST['value']);
$old_unit = ' inches';
$new_unit = 'cm';
break;
case "f-c":
$result = fahrenheit_to_celsius($_POST['value']);
$old_unit = ' Farenheit';
$new_unit = ' Celcius';
break;
case "c-f":
$result = celsius_to_fahrenheit($_POST['value']);
$old_unit = ' Celcius';
$new_unit = ' Farenheit';
break;
}
}
function fahrenheit_to_celsius($given_value) {
return 5/9*($given_value-32);
}
function celsius_to_fahrenheit($given_value) {
return $given_value*9/5+32;
}
function inches_to_centimeter($given_value) {
return $given_value/2.54;

I have several radio buttons which can be chosen and then the form can be sent without an issue. However a user can easily select the "Other" radio button and submit without giving any context or reason on why they chose it leaving the people receiving the "completed" form guessing what the issue is.
What I want to happen is that if a person selects the "Other" radio button and try and submit without a note/message/comment they will be interrupted with a requirement massage.
The snippet of the form that I want this to happen to is:
<label>
<input name="category" type="radio" value="Other" checked>Other
</label><br><br><br>
Note: <br> <textarea name="comment" rows="10" cols="70" placeholder="More detail... (Is there a way to recreate the error? What happened?)"></textarea>
<br><br>
<input type="submit" name="submit" value="Submit" class="userFriendly">
I have tried many variations of if statements and the required function given with HTML5 but can not seem to get what I need.
Any help will be appreciated and thanks in advance.

you can't use required method like that. I think your solution is add dynamically textbox when user clicked the option button like that:
Add this javascript function in your file:
<script language="javascript">
function activateNote()
{
var i = 1;
note_div.innerHTML = "Note: <br> <textarea required id='comment' name='comment' rows='10' cols='70' placeholder='More detail... (Is there a way to recreate the error? What happened?)' ></textarea><br><br>"
}
</script>
Change your elements like that, "delete note textarea" than add div element:
<label>
<input onClick="activateNote()" type="radio" name="category" value="Other">Other
</label>
<div id="note_div"></div>
One possible solution is to conditionally add the required HTML5 attribute to the required field when the "Other" radio button is selected.
You can do this with a javascript method attached to your radio button that is (de/)activated on select.

I'm writing a php form and I can't get the drop down boxes and check boxes to stick as in when I fill in my details but don't click something it will keep everything else filled but that one part that wasn't filled out. I can do it for the input text and radio buttons but I can't get it done for drop downs and checkboxes

Possibly a browser issue, however most browsers only require 'checked' at the end of the html input element for checkboxes. However you appear to be outputting checked = "checked" This is possibly the problem. Have a look at the sample below:
<?php
$name = isset($_GET['name']) ? $_GET['name'] : '';
$agree = isset($_GET['agree']) ? 'checked' : '';
$title = isset($_GET['title']) ? $_GET['title'] : '';
?>
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<form action="">
<input type="text" name="name" id="name" value="<?=$name;?>">
<input type="checkbox" name="agree" id="agree" <?=$agree;?>>
<select name="title" id="title">
<option value="Mr" <?=$title == 'Mr' ? 'selected' : ''?>>Mr</option>
<option value="Mrs" <?=$title == 'Mrs' ? 'selected' : ''?>>Mrs</option>
<option value="Miss" <?=$title == 'Miss' ? 'selected' : ''?>>Miss</option>
</select>
<button type="submit">submit</button>
</form>
</body>
</html>
After processing the values the output html should be as follows:
<form action="">
<input type="text" name="name" id="name" value="test">
<input type="checkbox" name="agree" id="agree" checked>
<select name="title" id="title">
<option value="Mr">Mr</option>
<option value="Mrs">Mrs</option>
<option value="Miss" selected>Miss</option>
</select>
<button type="submit">submit</button>
</form>
I found this site providing code for creating, reading, updating and deleting. I am confused about how to add checkboxes, radio buttons, and dropdowns
http://www.killersites.com/community/index.php?/topic/1969-basic-php-system-vieweditdeleteadd-records/
I'm not concerned with the pagination at all——my primary concern is to be able to put in two dropdowns, yes/no radio button, and a collection of 3 checkboxes using PHP.
My attempts were useless as when I tried to edit choices the values did not stay. Included are my three files: pets, editpets, and view.(I changed the file name for database, etc.)

I'm honestly lost at this point. I've been working on this for an entire month and I have no idea what I'm doing any more. I'd be so thankful if anyone can help me to edit this to work.
Thanks everyone.
Right, to get your saved results from the database I'm sure you're aware of how to do this.
For your radio buttons you're going to want to select your 'size' value from the database and use an if statement to determine which radio button will be 'checked'
forename/surname is a matter of simply getting the forename/surname from database and setting the appropriate input tags to the acquired values
You've already posted a technique for handling the combo/drop-down boxes
you'd perform a similar process for the 'type' checkboxes, compare your database values to the values of your checkbox input tags and if the value matches, set the checkbox to checked.
Next time please be more specific in what you are asking for help with and separate your code into segments that correspond with the files it is contained in.
if you have 3 files, have a code block for each file.
