Arduino通讯停止工作

Question

I am running a small WAMP server with Apache 2.2.22 and PHP 5.3.13. My problem is that my JavaScript/Ajax Code is no longer sending the $POST to my external PHP file which is supposed to then send the message via serial to my Arduino.

It was working perfectly fine, and then I simply changed the value of the input which is my 'Message' that I'm sending and suddenly it's not happy. I have had this problem before so I just changed the value back to its original, but now even that's not working. I tried to clear all my Web history, re-started WAMP server, and I even re-booted my computer, but none of it worked.

Anyway, here is my code:

HTML

    <div id="Room1Controls">
        <div id="ControlButton" class="Control1"><a>B
            A
            C
            K</a></div>
        <div class="Room1SwitchContainer">
            <div id="LightsSwitchBox" class="SwitchBox">
            <h1>Lights</h1>
            <input type="checkbox" class="SwitchButton1" value="L11"><a class="SButton1">On</a></input>
            <input type="checkbox" class="SwitchButton2" value="L10"><a class="SButton2">Off</a></input>
        </div>
        <div id="DoorsSwitchBox" class="SwitchBox">
            <h1>Doors</h1>
            <input type="checkbox" class="SwitchButton3" value="D10"><a class="SButton3">Open</a></input>
            <input type="checkbox" class="SwitchButton4" value="D11"><a class="SButton4">Lock</a></input>
        </div>
        <div id="BlindsSwitchBox" class="SwitchBox">
            <h1>Blinds</h1>
            <input type="checkbox" class="SwitchButton5" value="B11"><a class="SButton5">Open</a></input>
            <input type="checkbox" class="SwitchButton6" value="B10"><a class="SButton6">Close</a></input>
        </div>
    </div>
</div>

JavaScript/Ajax

$(document).ready(function(){
    var value;
    $(".SButton1").click(function(){
        $(".SwitchButton1").trigger('click');
    });
    $(".SButton2").click(function(){
        $(".SwitchButton2").trigger('click');
    });
    $(".SButton3").click(function(){
        $(".SwitchButton3").trigger('click');
    });
    $(".SButton4").click(function(){
        $(".SwitchButton4").trigger('click');
    });
    $(".SButton5").click(function(){
        $(".SwitchButton5").trigger('click');
    });
    $(".SButton6").click(function(){
        $(".SwitchButton6").trigger('click');
    });
    $("#Room1Controls input").click(function(){
        value=$(this).val();
        $.post('Inc/Parts/arduino.php',{message:value});
    });
});

PHP

<?php
    $message=$_POST['message'];

    if (isset($_POST['message'])) {
        require("php_serial.class.php");
        $serial = new phpSerial();
        $serial->deviceSet("COM3");
        exec('mode COM3 BAUD=96 PARITY=n DATA=8 STOP=1 xon=off octs=off rts=on');
        $serial->deviceOpen();
        if ($_POST['message'] == "L11") {
            $serial->sendMessage("L");
        } else if ($_POST['message'] == "L10") {
            $serial->sendMessage("l");
        } else if ($_POST['message'] == "D10") {
            $serial->sendMessage("D");
        } else if ($_POST['message'] == "D11") {
            $serial->sendMessage("d");
        } else if ($_POST['message'] == "B11") {
            $serial->sendMessage("B");
        } else if ($_POST['message'] == "B10") {
            $serial->sendMessage("b");
        }
        $serial->deviceClose();
    }
?>

And the code running on the Arduino Uno:

int ldr = 0;
int door = 13;
int blind = 12;
int led = 11;
int in = 0;

void setup() {
    pinMode(door, OUTPUT);
    pinMode(blind, OUTPUT);
    pinMode(led, OUTPUT);
    pinMode(ldr, INPUT);

    Serial.begin(9600);
}

void loop() {
    if (Serial.available() > 0) {
        in = Serial.read();
    }

    if (in == 'L')
    {
        int val = (analogRead(ldr));
        val = constrain(val, 150, 500);
        int LightLvl = map(val, 150, 500, 255, 0);
        analogWrite(led, LightLvl);
    }
    else
        if (in == 'l') (analogWrite(led, LOW));

    if (in == 'D')
    {
        digitalWrite(door, LOW);
    }
    else
        if (in == 'd') (digitalWrite(door, HIGH));

    if (in == 'B')
    {
      digitalWrite(blind, HIGH);
    }
    else
        if (in == 'b') (digitalWrite(blind, LOW));
}

If you could point out any inconsistency or errors in my code that would be great. Also, I am new to coding so if you have any suggestions for how I can improve my code to make it more efficient or alternative ways of doing things I would be very greatful.

Answer 1

Turns out my .htaccess file was the problem. I had some script to hide the extensions but for some reason the $POST Didn't like it.

Here is the code in the .htaccess file:

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s([^.]+)\.php [NC]
RewriteRule ^ %1 [R=301,L]
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^ %{REQUEST_URI}.php [L]
</IfModule>

If anyone knows a way around this i would love it if you shared it ;)
