I want to pass the name of the options by POST to another page. I used this but does not recognize the variable. 

echo "<form method=POST action=_search.php>";
echo "<select name=selectoption>";
    echo "<option value=nom>nome</option>";
    echo "<option value=prenom>ultimo</option>";
echo "</select>";
echo "<input type=submit name=btnsearch value=search >";
echo "</form>";

And on the other page to receive the value,

$var = $_POST['selectoption'];
echo $var;
php

  • The number of the selected option or all options? What error are you showing? I did a test with this code of yours and here it worked without errors.

  • I added the name in each option, and give me this error Undefined index: selectoption

  • 1

    already solved, was the name of the options. Thank you

Apparently, your problem is that you’re confusing value with the description of its <option> because I tested these two codes here and it’s working:

pregnant

and

nom

In this case, you have the option 'name' and 'last' only with values of 'nom' and 'prenom' which are the values returned by $_POST['selectoption'];

So if you want to receive 'name' and 'last' instead of 'nom' and 'prenom' you should use the following html in your <option>:

echo "<select name=selectoption>";
echo "<option value=nome>nome</option>";
echo "<option value=ultimo>ultimo</option>";
echo "</select>";

by submitting the form you will have as a result:

name

or

last

Observing:

I used your codes to perform the tests, so all the above statements are correct.
