Why does name="name[]" value="2013-01-01" split the value up into an array?

Hi there,

 

First, thank you for your interest in my problem, I appreciate your time.

 

I have a small form that is populated with records from a mysql database using php. I have three <input>'s which have the name attribute set to an array in case there is more than one record. The problem I'm having is for some reason the $adate (which is === "2013-01-01") gets broken down into 10 parts of an array. I don't get it, I've used this exact same setup on 5 or 6 other pages and it doesn't do this.

 

Just to be clear, when I echo out $date, it looks like this:

 

$date[$i] = 2

 

And when I run through it, it looks like this:

 

$date[0] = 2
$date[1] = 0
$date[2] = 1
$date[3] = 3
$date[4] = -
$date[5] = 0
$date[6] = 1
$date[7] = -
$date[8] = 0
$date[9] = 1

 

What I'm expecting, and wanting, is this:

 

$date[$i] = 2013-01-01

 

Here is my form code:

 

<form method="post" action="">
<table cellpadding="4" cellspacing="0" border="1" id="wod_tracking_form">

<tr align="center">
<td colspan="3"><?php echo $wod_name; ?> Tracking Form</td>
</tr>

<tr align="center">
<td class="bold">Date Worked</td>
<td class="bold">Notes</td>
<td class="bold">Entered By</td>
</tr>

<?php

for($i = $fromTIME; $i <= $toTIME; $i = strtotime('+1 day', $i))
   {
   $adate = date('Y-m-d',$i);
   $bdate = date('M jS Y',$i);
   echo "<tr>";
   echo "<td align=\"center\"><input type=\"hidden\" name=\"wod_date[]\" value=\"" . $adate . "\">" . $bdate . "</td>";
   echo "<td><textarea name=\"wod_note[]\" style=\"resize:none;\" maxlength=\"255\" cols=\"25\" rows=\"3\"><textarea></td>";
   //Change the value below once the admin area has been created. Use the session admin id here.
   echo "<td align=\"center\"><input type=\"hidden\" name=\"wod_admin\" value=\"10845\">10845</td>";
   echo "</tr>";
   }

?>

<tr align="center">
<td colspan="3"><input type="submit" name="wod_submit" style="width:100px;" value="SUBMIT"></td>
</tr>

</table>
</form>

 

Here is my code for inserting it into the database:

 

<?php
if(isset($_POST['wod_submit']))
   {
   $wod_date = $_POST['wod_date'];
   $note = $_POST['wod_note'];
   $admin = $_POST['wod_admin'];
   $i = 0;

   foreach($wod_date as $date)
       {
       $sql = ("INSERT INTO wod_tracking (Emp_ID, WOD_Date, WOD_Note, WOD_Admin) VALUES ('$emp_id', '$date[$i]', '$note[$i]', '$admin')");

       if(!$result_sql = $mysqli->query($sql))
           {
           die ("There was a problem inserting the records into the wod_tracking table. mySQLI Error: " . $mysqli->error . "");
           }

       $i++;
       }
   die;
   //unset($_SESSION['wod']);
   //redirect_to($url);
   }
?>

 

I don't know if this is because it's in a date format, or what, but it's causing me a lot of confusion, I would really appreciate some help on this one.

 

Cheers!

If it is dropdowns: Day, month & year, then catch it in an array and implode it:

 

$day = $_POST['day'];
$month = $_POST['month'];
$year = $_POST['year'];

$date = array($day, $month, $year);
$date = implode('-', $date);

 

Then you can just use the $date variable in your MySQL query to insert it into the database. This is the best way I know how. Maybe someone else knows a better solution?

I reckon seeing a view source of the form page could be helpfull, just to see what's in those hidden fields.

 

also, you have missed the / out of the closing tag for the textarea in the code you posted here.

 

Edt: Without the loop this is what the form source looks like on my machine:

<tr>
<td align="[url=""]center[/url]">
<input type="[url=""]hidden[/url]" name="[url=""]wod_date[][/url]" value="[url=""]2013-01-10[/url]">
Jan 10th 2013
</td>
<td>
<textarea name="[url=""]wod_note[][/url]" style="[url=""]resize:none;[/url]" maxlength="[url=""]255[/url]" cols="[url=""]25[/url]" rows="[url=""]3[/url]">
</textarea>
</td>
<td align="[url=""]center[/url]">
<input type="[url=""]hidden[/url]" name="[url=""]wod_admin[/url]" value="[url=""]10845[/url]">10845
</td>
</tr>

2nd Edt - ignore the URL's all through that, thatis the damn code formating on this board again :(

Thank you all for the replies.

 

I should have included what the variable are set to, sorry.

 

<?php
$fromSTR = $_SESSION['tod_fromDate']; //Selected through the date picker
$toSTR = $_SESSION['tod_toDate']; //Selected through the date picker. This is possibly the same value as $_SESSION['tod_fromDate']
$fromTIME = strtotime($fromSTR);
$toTIME = strtotime($toSTR);
$emp_id = $_SESSION['emp_id']; //Set from the database
?>

 

I have printed all of these out and they come out as expected:

 

<?php
$fromDate = 2013-01-01;
$toDate = 2013-01-01;
$emp_id = 9078;
?>

OK, here is my form code, all of it, including the $_SESSION's. I've added some echo statements.

 

<?php
$_SESSION['tod_fromDate'] = "2013-01-01";
$_SESSION['tod_toDate'] = "2013-01-01";
$fromSTR = $_SESSION['tod_fromDate'];
$toSTR = $_SESSION['tod_toDate'];
$fromTIME = strtotime($fromSTR);
$toTIME = strtotime($toSTR);
$_SESSION['emp_id'] = "9078";
$emp_id = $_SESSION['emp_id'];
$tod_name = "Taken Days Off";
$tod = 8;
?>
<form method="post" action="">
<table cellpadding="4" cellspacing="0" border="1" id="tod_tracking_form">
<tr align="center">
<td colspan="3"><?php echo $tod_name; ?> Tracking Form</td>
</tr>
<tr align="center">
<td class="bold">Date Taken</td>
<td class="bold">Notes</td>
<td class="bold">Entered By</td>
</tr>
<?php
for($i = $fromTIME; $i <= $toTIME; $i = strtotime('+1 day', $i))
{
echo "for i: " . $i . "<br>";//Error checking
$adate = date('Y-m-d',$i);
echo "for adate: " . $adate . "<br>";//Error checking
$bdate = date('M jS Y',$i);
echo "for bdate: " . $bdate . "<br>";//Error checking
echo "<tr>";
echo "<td align=\"center\"><input type=\"hidden\" name=\"tod_date[]\" value=\"" . $adate . "\">" . $bdate . "</td>";
echo "<td><textarea name=\"tod_note[]\" style=\"resize:none;\" maxlength=\"255\" cols=\"25\" rows=\"3\"></textarea></td>";
//Change the value below once the admin area has been created. Use the session admin id here.
echo "<td align=\"center\"><input type=\"hidden\" name=\"tod_admin\" value=\"10845\">10845</td>";
echo "</tr>";
}
?>
<tr align="center">
<td colspan="3"><input type="submit" name="tod_submit" style="width:100px;" value="SUBMIT"></td>
</tr>
</table>
</form>
<?php
if(isset($_POST['tod_submit']))
{
$tod_date = $_POST['tod_date'];
$note = $_POST['tod_note'];
$admin = $_POST['tod_admin'];
$i = 0;

foreach($tod_date as $date)
{
$sql = ("INSERT INTO tod_tracking (Emp_ID, TOD_Date, TOD_Note, TOD_Admin) VALUES ('$emp_id', '$date[$i]', '$note[$i]', '$admin')");
echo "foreach i: " . $i . "<br>";//Error checking
echo "foreach date[i]: " . $date[$i] . "<br>";//Error checking
// if(!$result_sql = $mysqli->query($sql))
// {
// die ("There was a problem inserting the records into the tod_tracking table. mySQLI Error: " . $mysqli->error . "");
// }
echo "sql: " . $sql . "<br>";//Error checking

$i++;
}
//unset($_SESSION['tod']);
//redirect_to($url);
}
?>

 

Now, here is the page source once the code has run:

 

<form method="post" action="">
<table cellpadding="4" cellspacing="0" border="1" id="tod_tracking_form">
<tr align="center">
<td colspan="3">Taken Days Off Tracking Form</td>
</tr>
<tr align="center">
<td class="bold">Date Taken</td>
<td class="bold">Notes</td>
<td class="bold">Entered By</td>
</tr>
for i: 1356998400<br>for adate: 2013-01-01<br>for bdate: Jan 1st 2013<br><tr><td align="center"><input type="hidden" name="tod_date[]" value="2013-01-01">Jan 1st 2013</td><td><textarea name="tod_note[]" style="resize:none;" maxlength="255" cols="25" rows="3"></textarea></td><td align="center"><input type="hidden" name="tod_admin" value="10845">10845</td></tr>
<tr align="center">
<td colspan="3"><input type="submit" name="tod_submit" style="width:100px;" value="SUBMIT"></td>
</tr>
</table>
</form>
foreach i: 0<br>foreach date[i]: 2<br>sql: INSERT INTO tod_tracking (Emp_ID, TOD_Date, TOD_Note, TOD_Admin) VALUES ('9078', '2', 'Here are the notes', '10845')<br>

 

And finally, here is a screen shot of the form with the echo statements:

This makes NO sense to me, I can't believe I'm either missing something obvious, or that I can't get it to work...ugh.

As I suspected... Run a var_dump () on $tod_date after this line:

$tod_date = $_POST['tod_date'];

 

Then have a look at your loop, and translate what it does to plain English. Make sure you really understand what it actually does, not just what you wanted it to do. ;)

 

Here it is:

array (size=1)
 0 => string '2013-01-01' (length=10)

"basic debugging 101" , ok, I guess my error checking wasn't cutting it? I echo'd out everything you did, I just didn't label which line it was on.

 

It's not that I don't appreciate getting helped in the right direction, or being taught how to troubleshoot instead of just being handed the answer...in fact I prefer that over just getting the answer...however the var_dump() and the "basic debugging 101" ideas didn't produce anything new that my already existing error checking didn't already have.

 

Anyways, I've found the problem. It was a stupid one as I'm sure we all expected.

 

Thanks for the help, I'm sorry if I sound unappreciative with my comment, don't take it personally.

EDIT: I forgot to say what the problem was. I changed $date[$i] to just $date in the insert statement and it worked fine.

You found the problem, but do you know what the problem was?

 

that which I echoed out was different to what you did, I'm not in the habbit of re-writing things for the fun of it or to pass the time. The point I was making was that you should be checking the content of the variable at each change.

 

Why did $date work when $date[$i] did not. What was $date[$i] if it wasn't what you expected it to be?

These are the key questions you need to be able to answer.

Right, I didn't really explain the solution very well.

 

The FOR loop was already looping through each value of the $date array. When I accidentally added the [$i] key to it, it broke that value down further thinking it was mutlidimensional array, when it wasn't.

To whoever last updated my fiddle, while I'm not a "faggot" as you claim, I'm also not a coward. You might think that updating the fiddle to say such a thing is funny and clever, but in reality it's just pathetic. If you have something to say, just say it and don't be such a juvenile.
