php and checkboxes

[shuini]

i have checkboxes in my script and i need to save the checked entries to my database.

i made the checkboxes an array.
the problem is, when i try to print the array, what prints is the name of the array itself and not the content of the array.

here's the code
$check_entries=array();
$check_entries=$_POST["check_entries"];

$check_count = count($check_entries);
print($check_count);

for($a=0; $a<$check_count; $a++)
{
print($check_entries[$a]);
}

output:
check_entriescheck_entries

output should be:
cat dog

[dreamcatcher]

How is your HTML code for the array? Should be:

<input type="checkbox" name="check_entries[]" value="cat">
<input type="checkbox" name="check_entries[]" value="dog">

Is that how you have it?

..and welcome to Webmaster World shuini :)

Also try to see what's really in the array:

foreach($check_entries as $name => $value)
{
echo "Name: $name &nbsp;&nbsp;&nbsp;Value: $value<br>";
}

Then you will know what is the field and it's value. Maybe as dreamcatcher suggested you have sth wrong with your html?

PS. The code you wrote should work

[shuini]

thanx for welcoming me.

anyway, this is the whole code

<?php
require_once("db.lib.php");
$link=db_open();

$sql="select * from tblentries where fldmarker!='deleted' ORDER BY fldeid";
$result=mysql_query($sql,$link);

while($row = mysql_fetch_array($result))
{
print('<tr>');
print('<td height="20">&nbsp;</td>');
print('<td colspan="3" align="center" valign="middle">'.$row["fldename"].'</td>');
rint('<td>&nbsp;</td>');
//HERE IS MY CHECKBOX,ITS ACTUALLY IN A LOOP SO I CAN'T REALLY NAME IT ALL COZ THE NAME WOULD ACTUALLY DEPEND ON THE LOOP
print('<td align="center" valign="middle"><input type="checkbox" name="check_entries[]" value="check_entries[]"></td>');
print('<td>&nbsp;</td>');
print('</tr>');
}
?>

AND THE FORM WHO RECEIVES IT HAS THIS

$check_entries=array();
$check_entries=$_POST["check_entries"];

$check_count = count($check_entries);
print($check_count);

print($check_entries[0]);
print($check_entries[1]);

for($a=0; $a<$check_count; $a++)
{
//if (isset($_POST['check_entries[$a]' . $i]))
//{
print($check_entries[$a]);
//}
}

IT PRINTS CHECK_ENTRIES OVER AND OVER AGAIN

[mcibor]

And it should print that out, as it's what is in the checkbox
You have:

print('<td align="center" valign="middle"><input type="checkbox" name="check_entries[]" value="check_entries[]"></td>');

I think you should have:

print('<td align="center" valign="middle"><input type="checkbox" name="check_entries[]" value="'.$row["fldename"].'"></td>');

If not this part of row, then put there something else that should be there, not the value="check_entries"

yep, i tried that already.

and it prints
row["fldename"]

y can't it print the value of ename? how do i do that?

[dreamcatcher]

Have you included the $ with the variable?

$row["fldename"]

What mcibor posted should work ok.

[mcibor]

Write exactly as below (with every single quote)

value="' . $row["fldename"] . '"></td>')

that is: after value you must have double quote: ", and then single quote: '.
It is because if you write:

$v = "Kate";
echo "Welcome $v";// Welcome Kate - the parser will see that it's the variable. However

echo 'Welcome $v';// Welcome $v - the parser thinks this is only text, no variables in it!

So to correct the second:

echo 'Welcome '.$v;// Welcome Kate

Hope this cleares the things up for you!
