I want to pass a form via json to my php and then insert the data into the database.
function enviaDados(form){
var dados = document.getElementById('form');
console.log(dados.categoria.value);
$.ajax({
type: "POST",
data: "teste do json mo louco",
url: "includes/post.php",
success: function(msg){
console.log(dados.categoria.value);
}
});
alert("sadfdsaf");
}
How do I read this json in my php?
To retrieve data from your form, you can use the serialize() function. Here's an example of how to use:
function enviaDados(form){
var dados = document.getElementById('form');
console.log(dados.categoria.value);
$.ajax({
type: "POST",
data: $('#myForm').serialize(),
url: "includes/post.php",
success: function(msg){
console.log(dados.categoria.value);
}
});
alert("sadfdsaf");
}
This function will take all the values of your form and mount a structure chave valor , where the key is the name attribute of <inputs>
In your PHP script you will retrieve the values using the super global $ _POST. Let's take an example. Suppose you have the following form:
<form method="post" id="myForm">
Seu nome: <input type="text" name="nome">
</form>
In php you could retrieve the information entered in the name field as follows:
$nome = $_POST['nome'];
If you are expecting a string: $ string = file_get_contents ('php: // input');
If you're expecting an object, use json_decode .
