How to check if checkbox is checked php
Question
This is html code for my checkbox and button
<form>
<input type="checkbox" id="DNA" name="DNA" value="checkox_value">
<button type="button" name="submit" onClick="search()" id="sim_btn" class="btn btn-primary">Start Simulation</button>
</form>
I want to check if checkbox is checked and if yes write the input to my file.
I tried using the isset function but it doesn't work any other suggestions?
if(isset($_POST["DNA"])) {
$input3 = "signal(f).";
fwrite($handleStoryFile, $input3 . PHP_EOL);
}
