Updating MYSQL DB with checkbox and textarea data (in PHP) - php

Question

I'm using a table to update a database, the table has 264 checkboxes which can be checked and unchecked then updated on the database.
I'm doing this by posting data on the form, using a while loop to set all fields to blank ( the value of the checkbox and the textarea value) for each respective field, then using a foreach loop to update each row in the database with the value of the checkbox.
Now, what I want to do is add the textarea value for each ticked checkbox into the database as well, what i cant figure out is how to do this?
This is my update code:
if (isset($_POST["update"])) {
$seolistRes2 = mysql_query($seolistQ) or die(mysql_error());
while ($seolistRow2 = mysql_fetch_array($seolistRes2)) {
$wsID1 = $seolistRow2["worksheetID"];
$updateWSQ2 = "UPDATE seo_work SET taskValue=0, taskInfo='' WHERE worksheetID=$wsID1 AND userID=$userID";
mysql_query($updateWSQ2) or die(mysql_error());
}
$item = $_POST;
foreach($item as $key => $value) {
$wsID = str_replace("checkbox","",$key);
if (is_numeric($wsID)) {
$updateWSQ = "UPDATE seo_work SET taskValue=$value taskInfo=$value WHERE worksheetID=$wsID AND userID=$userID";
mysql_query($updateWSQ) or die(mysql_error());
header("Location: worksheet.php?y=".$seoworkyear."&userID=$userID&action=success");
}
}
}
This is checkbox and textarea code: (please note this is within a form)
$currentTask = '';
echo "<tr class='tr'>";
while ($seolistRow = mysql_fetch_array($seolistRes)) {
$taskValue = $seolistRow["taskValue"];
$worksheetID = $seolistRow["worksheetID"];
$taskName = $seolistRow["taskName"];
$taskInfo = $seolistRow["taskInfo"];
if ($taskValue == 1) {
$taskDone = "<input type='checkbox' value='1' class='checkbox' name='checkbox".$worksheetID."' id=checkbox'".$worksheetID."' checked='checked' />".
"<textarea class='textarea' name='textarea".$worksheetID."' id=textarea'".$worksheetID."'>" . $taskInfo . "</textarea>";
}
else {
$taskDone = "<input type='checkbox' value='1' class='checkbox' name='checkbox".$worksheetID."' id='checkbox".$worksheetID."' />".
"<textarea class='textarea' name='textarea".$worksheetID."' id=textarea'".$worksheetID."'>" . $taskInfo . "</textarea>";
}
if ($currentTask != $taskName) {
echo "</tr>";
echo "<tr class='tr'>";
echo "<td class='task'>".$taskName."</td>";
}
echo "<td class='tick'>".$taskDone."</td>";
$currentTask = $taskName;
}
echo "</tr>";

Use your HTML form like shown below.
$currentTask = '';
echo "<tr class='tr'>";
while ($seolistRow = mysql_fetch_array($seolistRes)) {
$taskValue = $seolistRow["taskValue"];
$worksheetID = $seolistRow["worksheetID"];
$taskName = $seolistRow["taskName"];
$taskInfo = $seolistRow["taskInfo"];
if ($taskValue == 1) {
$taskDone = "<input type='checkbox' value='1' class='checkbox' name='checkbox[".$worksheetID."]' id='checkbox[".$worksheetID."]' checked='checked' />".
"<textarea class='textarea' name='textarea[".$worksheetID."]' id='textarea[".$worksheetID."]'>" . $taskInfo . "</textarea>";
}
else {
$taskDone = "<input type='checkbox' value='1' class='checkbox' name='checkbox[".$worksheetID."]' id='checkbox[".$worksheetID."]' />".
"<textarea class='textarea' name='textarea[".$worksheetID."]' id='textarea[".$worksheetID."]'>" . $taskInfo . "</textarea>";
}
if ($currentTask != $taskName) {
echo "</tr>";
echo "<tr class='tr'>";
echo "<td class='task'>".$taskName."</td>";
}
echo "<td class='tick'>".$taskDone."</td>";
$currentTask = $taskName;
}
echo "</tr>";
See the modified name and id of your textarea and checkbox. I have modified it to textarea[SOME_WORKSHEET_ID] and checkbox[SOME_WORKSHEET_ID] respectively.
So, when you submit the form, you will receive those checkbox and textarea value as an array, with worksheetId as an index. You can use this [] technique to retrieve the values of the textarea and checkbox, or as many field you want to add in form.
Use above HTML structure and check the $_POST array.
Hope this will help..

You should be able to get the value in the textarea using $_POST['textarea' . $wsID] after your call to is_numeric.

Here is another approach, not completely tested, but hopefully you get the idea...
if (isset($_POST["update"]))
{
// All to blank
$seolistRes2 = mysql_query($seolistQ) or die(mysql_error());
while ($seolistRow2 = mysql_fetch_array($seolistRes2))
{
$wsID1 = $seolistRow2["worksheetID"];
$updateWSQ2 = "UPDATE seo_work SET taskValue=0, taskInfo='' WHERE worksheetID=$wsID1 AND userID=$userID";
mysql_query($updateWSQ2) or die(mysql_error());
}
// Re use your result from the select to go through all the known IDs
foreach($seolistRow2 as $i => $data)
{
// Obtain the ID
$id = $data['worksheetID'];
// Get the checkbox value for current ID
$checkbox_wsID = $_POST['checkbox' . $id];
// Get the textarea value for current ID
$textarea_wsID = $_POST['textarea' . $id];
// Update the Row using mysql_escape
$updateWSQ = "UPDATE seo_work " .
"SET taskValue = '" . mysql_escape_string($checkbox_wsID) ."' taskInfo = '" . mysql_escape_string($textarea_wsID) ."'" .
"WHERE worksheetID=$id AND userID=$userID";
mysql_query($updateWSQ)
or die(mysql_error());
header("Location: worksheet.php?y=".$seoworkyear."&userID=$userID&action=success");
}
}
