[SOLVED] $_POST help

[apot]

I need help with $_POST

 

I'm trying to pass a variable into a form and cannot get the data from $_FORM using the same variable.  Is this because I can't pass a variable into a form name?

 

$i = 1;

 

<?php

echo "<form><input type=\"text\" name=\"name$i\">";

echo "<input type=\"submit\" name\"submit\" value=\"submit\"></form>";

?>

 

have also tried:

 

$i = 1;

 

<?php

echo "<form><input type=\"text\" name=\"name$i\">";

echo "<input type=\"submit\" name\"submit\" value=\"submit\"></form>";

?>

 

now getting the information:

 

<?php

$name = $_POST['name1'];

echo $name;

?>

 

Is this possible? If not is there another way to do it?

 

thanks

You need to tell the form where to go...

<form method="POST" action='myfile.php'>

else it all looks ok... Just remember to check what you get!

[apot]

sorry I did have action="myfile.php in my script. I just quickly wrote that code to describe what i was talking about and forgot to write that in. Anything else you see wrong?

yah you are need to define the POST method in your form tags because most browser default to GET

 

i would also suggest escaping you text for the variable

 

echo "<form><input type=\"text\" name=\"name" . $i . "\">";

 

and possable useing a single quote to save on the \ (cant use to many stocks are limited)

 

echo '<form><input type="text" name="name"' . $i . '">';

you must specified method="POST" in form tag

default is GET

 

and $i = 1 must be inside <?php tag

[apot]

I have made all those corrections and now i am trying to get the post info while using a variable.

 

<?php
$i = 1;
$name = $_POST['name$i'];
?>

 

have also tried:

 

<?php
$i = 1;
$name = $_POST['name.$i'];
?>

 

Is this possible?

[marcus]

print_r($_POST);

 

Or run a loop to see which value exists.

 

<?php
for($i=1;$i<=50;$i++){
   if($_POST['name' . $i]){
   echo $_POST['name' . $i] . " exists<br />\n";
   }
}
?>
<?php
$ran = rand(1,50);
?>
<form method="post">
<input type="text" name="name<?=$ran?>" value="<?=$ran?>">
<input type="submit">
</form>

[sasa]

try

$name = $_POST["name$i"];

or

$name = $_POST['name'.$i];

[marcus]

@sasa, either way works.

[apot]

sweet the

 

$_POST['name'.$i];

 

worked perfect. it works now!

 

Thanks a lot!!
