Display keywords from DB as Checkbox Options - php

Question

I've created a database using mysqli and I have keywords stored in a table called "Keywords". I need to use the keywords stored in this table to display as options on a form in the form of checkboxes.
So, if the keyword has not been added to the db, then the checkbox on the form will not display for users to choose from. What's the best way to achieve this? My sql knowledge is basic but I can have an idea on how the query might look. Just not sure about how to display them as checkboxes.
UPDATE UPDATE UPDATE!
I was able to get my array to display with checkboxes: Here is what I did:
<?php
include 'db.php';
$sql = mysqli_query($con,"SELECT * FROM addKeywordTable ORDER BY Keyword_Name ASC");
print <<<HERE
HERE;
while ($row = mysqli_fetch_array($sql))
{
$key = $row['Keyword_Name'];
$id = $row["keyID"];
print <<<HERE
<input type="checkbox" id="$key">$key<br />
HERE;
}
?>
NOW MY QUESTION IS: How do I pass the checked value off to my new table (profileTable) a completely separate table containing the form results?
MY FORM CODE LOOKS LIKE THIS (Fri 8/9/13):
<div id="form1profile">
<form method="post" enctype="multipart/form-data" name="addProfile" id="addProfile" >
<fieldset>
<legend>Add/Create a Media Source Profile</legend>
<br>
<table width="400" border="0" align="center" cellpadding="0" cellspacing="0">
<tr>
<th ><label>First Name</label></th>
<td><input name="FName" type="text" id="FName" size="40"></td>
</tr>
<tr>
<th >Middle Name</th>
<td><input name="MName" type="text" id="MName" size="40"></td>
</tr>
<tr>
<th ><label>Last<br>
Name</label></th>
<td><input name="LName" type="text" id="LName" size="40"></td>
</tr>
<tr>
<th><label>Prefix</label></th>
<td><input name="Prefix" type="text" id="Prefix" size="40"></td>
</tr>
<tr>
<th><label>Title
</label></th>
<td><input name="Title" type="text" id="Title" size="40"></td>
</tr>
<tr>

</tr>
<tr>
<th><label>Other Phone</label></th>
<td><input name="PH2" type="text" id="PH2" size="40"></td>
</tr>
<tr>
<th><label>Email</label></th>
<td><input name="Email" type="text" id="Email" size="40"></td>
</tr>
<tr>
<th><label for="ProfileImg">Photo</label></th>
<td><input name="ProfileImg" type="file" multiple id="ProfileImg" form="addProfile">
</td>
</tr>
<tr>
<th valign="top"><label class="biotextTitle">Bio/Info</label></th>
<td><textarea name="bioLinks" cols="55" rows="25" id="bioLinks" placeholder="Paste Bio/Links here..."></textarea></td>
</tr>
<tr>
<th><label class="Keywords">Keyword</label></th>
<td>
<?php include 'db.php';
$sql = mysqli_query($con,"SELECT * FROM addKeywordTable ORDER BY Keyword_Name ASC");
foreach ($_POST['keyword'] as $keyword) {
if ($keyword) {
// $keyword is a selected keyword
}
}
while ($row = mysqli_fetch_array($sql))
{
$key = $row['Keyword_Name'];
$id = $row["keyID"];
print <<<HERE
<input type="checkbox" name="keyword[$key]" id="$key">$key<br />
HERE;
}
?>
</td>
</tr>
<tr>
<th><label class="tags">Tags</label></th>
<td><input name="Tags" type="text" id="Tags" size="40"></td>
</tr>
<tr>
<th><input name="SaveBtn" type="submit" id="SaveBtn" formaction="insertProfile.php" formmethod="POST" value="Save"></th>
<td></td>
</tr>
</table>
<br />
</fieldset>
</form>
</div>

Answer 1

You may add a name to your checkboxes:
<input type="checkbox" name="keyword[$key]" value="1">$key<br />
Doing so, when the page is submit you just need to iterate through the selected keywords:
foreach ($_POST['keyword'] as $keyword) {
if ($keyword) {
// $keyword is a selected keyword
}
}
After that you can get all the selected keywords, then you shall just insert them into your table.

Answer 2

change this --
print <<<HERE
<input type="checkbox" id="$key">$key<br />
HERE;
to this
echo "<input type='checkbox' id='tag_$id'>$key<br />";
reason for doing this is so you eliminate all character combinations by just using numeric only. character combo for EX. id="Ava/Flight", id="Ava Flight"
