How can I echo out the value stored in my radio button from my database?

Question

I'm trying to echo out the current value of the gender of particular data and edit the gender if the user want to. How can I do that with this code?

Here is my code:

    echo "Gender: <label class=\"radio-inline\"><input type=\"radio\" name=\"gender\" value=\"Male\" > Male</label>
                  <label class=\"radio-inline\"><input type=\"radio\" name=\"gender\" value=\"Female\"> Female</label><br/>";

Below is the whole code for how I get all the information in my database:

       <?php 
        while(mysqli_stmt_fetch($stmt1)) {
        echo "First Name: <input type=\"text\" style=\"border: none; border-color: transparent;\" value=\"$first_name\"><br/>";
        echo "Middle Name: <input type=\"text\" style=\"border: none; border-color: transparent;\" value=\"$middle_name\"><br/>";
        echo "Last Name: <input type=\"text\" style=\"border: none; border-color: transparent;\" value=\"$last_name\"><br/>";
        echo "Age: <input type=\"text\" style=\"border: none; border-color: transparent;\" value=\"$age\"><br/>";
        echo "Birth Date: <select name=\"month\"  style=\"width:auto;\">
                          <option value=\"$month\"></option>
                          <option value=\"January\">January</option>

Answer 1

Suppose you stored 1 for male and 0 for female in your database table then then the code fetched from your database can be implemented as :

<input type="radio" name="gender" <?php echo $row['gender'] === '1' ?'checked="checked"':'';?>/> Male
<input type="radio" name="gender" <?php echo $row['gender'] === '0' ?'checked="checked"':'';?>/> Female

Thats it. If male is stored in the database then first one will be checked else second one will be checked.

Answer 2

try something like this use single quotes for echo and use double quotes for values its easy to do .

    <?php

    $gender = 'Male';

    echo 'Gender: <label class="radio-inline">
                   <input type="radio" name="gender" value="Male"';
                   if(isset($gender) && $gender == 'Male') { echo 'checked="checked"'; }
     echo ' > Male</label>
                  <label class="radio-inline">
                  <input type="radio" name="gender" value="Female" ';
                  if(isset($gender) && $gender == 'Female') { echo 'checked="checked"'; }
      echo '> Female</label><br/>';

    ?>

Answer 3

Use an if condition in radio button to select your stored value like

$gender = 'Female';
echo "Gender: <label class=\"radio-inline\">
               <input type=\"radio\" name=\"gender\" value=\"Male\" ";
               if(isset($gender) && $gender == 'Male') { echo 'checked';}
 echo " > Male</label>
              <label class=\"radio-inline\">
              <input type=\"radio\" name=\"gender\" value=\"Female\" ";
              if(isset($gender) && $gender == 'Female') { echo 'checked';}
  echo "> Female</label><br/>";
