How to use if/Else within a function?

Question

I’m trying to create a simple function, to write the title according to the gender selection on the form, but I must be doing something wrong:

$sexo = empty($_POST['sexo']) ? "[sexo]" : $_POST['sexo'];

function mudasexo($sexo) {

    if ($sexo == "masculino") {
            echo "O senhor";
        }
    else {
        echo "A senhora";
    }
}

Hence I wanted to use this function within HTML texts with: <?php mudasexo() ?> but it is not working. It does not accuse any error when threshing, but the page doesn’t even open.

Answer 1

I would do different, I see several conceptual errors in the function, but the only problem that prevents it from working is the function call in HTML, the function expects a parameter, you are not passing any arguments. I think this is your argument:

<?php mudasexo(empty($_POST['sexo']) ? "[sexo]" : $_POST['sexo']) ?>

I put in the Github for future reference.

Even with the problem, if nothing is appearing then there are problems in other parts of the code.

According to the comments, the real problem was in the function statement but still worth rethinking it.

Answer 2

You can do it this way:

function mudarSexo($sexo){

    switch($sexo){
        default: 
            $mudanca = 'Sexo não selecionado';
            break;

        case 'masculino':
            $mudanca = 'Senhor';
            break;

        case 'feminino':
            $mudanca = 'Senhora';
            break;      
    }

    return $mudanca;
}

echo mudarSexo("masculino"); // Imprime -> Senhor
echo mudarSexo("feminino"); // Imprime -> Senhora
echo mudarSexo(""); // Imprime -> Sexo não selecionado

Answer 3

I have a form , individual, appears one and for legal person appears another. It’s in html, I don’t know how to fit the if and Else in the middle of it. I even tried but it’s giving error.

the individual example:

Juridical Person Pessoa Física

        <?php
        <if value == (pessoa física)>
        <br>


        <div class="row">
            <div class="col">
                <label>CPF</label>  
                <input  name="cpf" type="text" placeholder="Digite o CPF" class="form-control input-md" required>
            </div>
            <br>
            <div class="col">
                <label>E-mail</label>
