HTML form multiple fields

[sergiobgd]

I have html form that looks like:

<form method="post" action="?a=up">
...some mysql query...
while ($i = mysql_fetch_array($result)) {

<input name="name[]" type="text" value="<?=$i['name'];?>" />
<input name="years[]" type="text" value="<?=abs($age);?>"/>
<input name="to[]" type="checkbox" value="<?=$i['id'];?>" />

}
<input name="" type="submit" value="go" />
</form>

 

 

The problem I have is that I can not get the values of the form fields such as "name" and "years". I can only get a list of the ids (value of "to" checkbox).

 

The php code looks like:

$cnt = 0;
for($p = 0; $p <= (sizeof($to)-1); $p++)
{
echo $to[$p].$name[$p].$years[$p]"<br>";
$cnt++;
}

$tm = array($cnt);

 

 

What I'm doing wrong?

you haven't set the variables in the processing script

 

// one example
$to = $_POST['to'];

[sergiobgd]

I tried with:

if ($_SERVER['REQUEST_METHOD'] === 'POST'){
  $cnt = 0;
  for($p = 0; $p <= (sizeof($_POST['to'])-1); $p++)
  {
    if (isset($_POST['to'][$p]))
    {
      echo $_POST['to'][$p] . $_POST['name'][$p] . $_POST['years'][$p] . "<br>";
      $cnt++;
    }
  }

  $tm = array($cnt);
}

 

I get the same result.

All values in the form are correct. As I said, everything is working fine if I want to get only the list of selected "to" fields. If I try to get the "name" and "years" it doesn't work. I always get the correct TO value and the name and year of the first (not checked) field in form.

 

[BlueSkyIS]

have you done View Source in the browser to view the values of the form fields to ensure they look correct?

 

also, you shouldn't use php short tags. you'll be happier later if you do something more like:

 

<input name="name[]" type="text" value="<?php echo $i['name'];?>" />
<input name="years[]" type="text" value="<?php echo abs($age);?>"/>
<input name="to[]" type="checkbox" value="<?php echo $i['id'];?>" />

 

perhaps just to cut to the chase, you might try this just above your code to make sure the values are coming across:

 

print_r($_POST);

 

that will tell you right away what values are getting posted.

[sergiobgd]

The result of print_r($_POST); is:

Array ( [name] => Array ( [0] => john [1] => mike [2] => any [3] => leo [4] => marija ) [years] => Array ( [0] => 26 [1] => 44 [2] => 46 [3] => 32 [4] => 25 )[to] => Array ( [0] => 113807 [1] => 113784 ) ) 

 

Value of "to" fields are the two that are marked.

I'm not sure exactly what you want... but maybe this helps... and sorry if I write something wrong. It's done in a hurry and it's quite much!

 

echo '<form method="post" action="?a=up">';
$n=0;
while($i=mysql_fetch_array($result)){
echo '
<input name="name'.$n.'" type="text" value="'.$i['name'].'" />
<input name="years'.$n.'" type="text" value="'.$i['age'].'" />
<input name="to'.$n.'" type="checkbox" value="'.$i['id'].'" />';
$n++;
}
echo '<input name="" type="submit" value="go" />
</form>';

 

 

You will need to know how many rows the person got when the people were listed. Do that with a mysql query.

$nr=mysql_num_rows($result);
$n=0;
for($i=0;$i<$nr;$i++){
if(!empty($_POST['to'.$i])){
	if(!empty($_POST['name'.$i])){
		if(!empty($_POST['years'.$i])){
			echo $_POST['to'.$i].$_POST['name'.$i].$_POST['years'.$i];
			$to[]=$_POST['to'.$i];
			$name[]=$_POST['name'.$i];
			$years[]=$_POST['years'.$i];
			$n++;
		}
	}
}
}
echo $n;
print_r($to);
print_r($name);
print_r($years);
echo $to[0];

I want to get the values of other fields that are related to a specific person (name, age) where the checkbox is marked.

Now, I can only get correct the "to" value of members whose checkbox is marked, but other values of specific member is wrong (name, years). As result I always get correct the "to" value (those selected in the form members) but the "name" and "years" are for the first one in the form fild.

[MMDE]

eh? did you try what I wrote and messed around a bit with it?

[sergiobgd]

Yes I did. I used $nr=sizeof($to) to get the numbers of selected checkboxes.

 

The result I got was:

Array ( [0] => 26 [1] => 44 [2] => 46 [3] => 32 [4] => 25) Array ( [0] => john [1] => mike [2] => any [3] => ely [4] => maria) Array ( [0] => 26 [1] => 44 [2] => 46 [3] => 32 [4] => 25) 

 

 

I get correct values of selected checkboxes in php code that I'm using, why can I get the correct values of name and years field?

 

[MMDE]

I did some problem solving for you in my code, a quite okay workaround for an annoying problem.

 

The thing is, you try to send the same variable twice. It will only read one of them I think. The later one.

 

Test this:

<?php
echo '<form method="post" action="">';
for($i=0;$i<10;$i++){
echo '<input type="hidden" name="test" value="sample'.$i.'" />';
}
echo '<input type="submit" value="submit" /></form>';
if(!empty($_POST['test'])){
echo $_POST['test'].'<br />';
echo sizeof($_POST['test']).'<br />';
echo count($_POST['test']).'<br />';
print_r($_POST['test']);
}
?>

 

I at least get this as result:

sample9
1
1
sample9

[sergiobgd]

If I add one or two more fields in this while loop, something like:

 

for($i=0;$i<10;$i++){
echo '<input type="hidden" name="test" value="sample'.$i.'" />';
        echo '<input type="hidden" name="name" value="john'.$i.'" />';
        echo '<input name="to" type="checkbox" value="'.$i.'" />';
}

 

How can I get the values of "name" and checkbox of the selected fields?

[MMDE]

dude, you clearly haven't really looked at what I've sent you.

 

You can only access the last one of the inputs with the same name.

 

As I stated earlier, I wrote and showed you a workaround. Now please look at it, test it and mess around with it. That is how you learn.
