I have the following code:

HTML:

<input name="dataInicio" type="text" class="form-control datepicker" placeholder="Data" maxlength="10" autocomplete="off" />
<input name="dataFim" type="text" class="form-control datepicker" placeholder="Data" maxlength="10" autocomplete="off" />

MySQL

'date' DATE NOT NULL,

PHP

$dataInicio = (isset($_POST['dataInicio'])) ? '2017-09-25' : date("Y-m-d", strtotime($_POST['dataInicio']));
$dataFim = (isset($_POST['dataFim'])) ? date("Y-m-d") : date("Y-m-d", strtotime($_POST['dataFim']));

And finally the test I'm doing to return the range of days I need:

PHP

SELECT date,time,resultCode,hostname,user,sites,qt_acessos,bytes
                FROM tblResumo
                WHERE 
                    date >= '$dataInicio' AND 
                    date <= '$dataFim'

But I have the return of ALL the records, regardless of the date entered in the application form! And what I do not understand is that by checking in the POST, the values entered for the date range are there correctly. I am printing the values as JSON, if this information is useful. Where am I going wrong? I anticipate my thanks.

There is a field of type date in html:

<input type="date">

This will standardize the information passed in the field, instead of being validated later if it is all numbers for example.

In SELECT you can use the SQL command BETWEEN :

This command takes values between past param- eters, such as dates. Example:

SELECT * FROM tabela WHERE data BETWEEN '2017-01-01' AND '2017-01-31';

Note: There is a Jquery UI function called a datepicker where you can optimize the entire date field.

Why does this strange result appear when printing the values defined in the class? (Python) Bootstrap menu does not work

There is a problem in defining the variables $dataInicio and $dataFim . The ternary operator returns '2017-09-25' and date("Y-m-d") if exists data in the corresponding $_POST item.

I suppose you want to fill in '2017-09-25' or date("Y-m-d") (today) if does not exist data in the $_POST array. Therefore, using !isset() :

$dataInicio = (!isset($_POST['dataInicio'])) ? '2017-09-25' : date("Y-m-d", strtotime($_POST['dataInicio']));
$dataFim = (!isset($_POST['dataFim'])) ? date("Y-m-d") : date("Y-m-d", strtotime($_POST['dataFim']));
