Show Specials between certain times / days of the week.

[hinchcliffe]

Hello,

I'm kind of a noob at php. I'm trying to write some code that shows what a restaurant special is between certain times of the week and it switches depending on the day of the week as well.

 

Each day of the week will have different specials. There's a breakfast special between 6am-11am, then there's a lunch special between 11am-4pm, then there's a dinner special from 4pm - 11pm.

 

Anyways I've been struggling with some code, could someone take a look at it and help me out? Thanks!

 

<?php

$day = (date("D"));
$time = (date("H") + 2);


// Actuall Specials

// Mon
if ($day = 'Mon' && $time == (11 > $time && $time > 0)) {
    $special = 'Monday Breakfast Special';
}

if ($day = 'Mon' && $time == (16 > $time && $time > 11)) {
    $special = 'Monday Lunch Special';
}

if ($day = 'Mon' && $time == (24 > $time && $time >= 16)) {
    $special = 'Monday Dinner Special';
}

// Tue
if ($day = 'Tue' && $time == (11 > $time && $time > 0)) {
    $special = 'Tuesday Breakfast Special';
}

if ($day = 'Tue' && $time == (16 > $time && $time > 11)) {
    $special = 'Tuesday Lunch Special';
}

if ($day = 'Tue' && $time == (24 > $time && $time >= 16)) {
    $special = 'Tuesday Dinner Special';
}

// Wed
if ($day = 'Wed' && $time == (11 > $time && $time > 0)) {
    $special = 'Wednesday Breakfast Special';
}

if ($day = 'Wed' && $time == (16 > $time && $time > 11)) {
    $special = 'Wednesday Lunch Special';
}

if ($day = 'Wed' && $time == (24 > $time && $time >= 16)) {
    $special = 'Wednesday Dinner Special';
}

// Thu
if ($day = 'Thu' && $time == (11 > $time && $time > 0)) {
    $special = 'Thursday Breakfast Special';
}

if ($day = 'Thu' && $time == (16 > $time && $time > 11)) {
    $special = 'Thursday Lunch Special';
}

if ($day = 'Thu' && $time == (24 > $time && $time >= 16)) {
    $special = 'Thursday Dinner Special';
}

// Fri
if ($day = 'Fri' && $time == (11 > $time && $time > 0)) {
    $special = 'Friday Breakfast Special';
}

if ($day = 'Fri' && $time == (16 > $time && $time > 11)) {
    $special = 'Friday Lunch Special';
}

if ($day = 'Fri' && $time == (24 > $time && $time >= 16)) {
    $special = 'Friday Dinner Special';
}

// Sat
if ($day = 'Sat' && $time == (11 > $time && $time > 0)) {
    $special = 'Saturday Breakfast Special';
}

if ($day = 'Sat' && $time == (16 > $time && $time > 11)) {
    $special = 'Saturday Lunch Special';
}

if ($day = 'Sat' && $time == (24 > $time && $time >= 16)) {
    $special = 'Saturday Dinner Special';
}

// Sun
if ($day = 'Sun' && $time == (11 > $time && $time > 0)) {
    $special = 'Sunday Breakfast Special';
}

if ($day = 'Sun' && $time == (16 > $time && $time > 11)) {
    $special = 'Sunday Lunch Special';
}

if ($day = 'Sun' && $time == (24 > $time && $time >= 16)) {
    $special = 'Sunday Dinner Special';
}

echo $day;
echo ('<br /><br />');
echo $time;
echo ('<br /><br />');
echo $special;
?> 

 

Any help teaching me would be very appreciated.

So what happens now? What is the actual problem?

[hinchcliffe]

Ok,

So what's happening is... It's showing the very last day & not filtering the day if statement.

 

So right now it's supposed to be showing Thursday, Breakfast Special

It's showing Sunday, Breakfast Special.

 

Oh it's also not echo'ing the day*.

 

Know what's wrong?

[roopurt18]

It doesn't echo the special because his variable $special is empty.

 

It's empty because his if conditions are all written incorrectly and none of them are passing or the wrong one(s) are passing.

 

If you want to check if $time is between, for example, 9 and 15 inclusive, you'd use:

if( $time >= 9 && $time <= 15 ) {

Cool Thanks, Roopurt.

 

Here's the code I have now that works. 

 

<?php

$day = (date("D"));
$time = (date("H") + 2);


// Actuall Specials
// Test Code if( $time >= 9 && $time <= 15 ) {


// Mon

if ($day == 'Mon'){
if ($time >= 0 && $time <= 11 ) {
    $special = 'Monday Breakfast Special';
}}

if ($day == 'Mon'){
if ($time >= 11 && $time <= 16 ) {
    $special = 'Monday Lunch Special';
}}

if ($day == 'Mon'){
if ($time >= 16 && $time <= 24 ) {
    $special = 'Monday Dinner Special';
}}

// Tue
if ($day == 'Tue'){
if ($time >= 0 && $time <= 11 ) {
    $special = 'Tuesday Breakfast Special';
}}

if ($day == 'Tue'){
if ($time >= 11 && $time <= 16 ) {
    $special = 'Tuesday Lunch Special';
}}

if ($day == 'Tue'){
if ($time >= 16 && $time <= 24 ) {
    $special = 'Tuesday Dinner Special';
}}

// Wed
if ($day == 'Wed'){
if ($time >= 0 && $time <= 11 ) {
    $special = 'Wednesday Breakfast Special';
}}

if ($day == 'Wed'){
if ($time >= 11 && $time <= 16 ) {
    $special = 'Wednesday Lunch Special';
}}

if ($day == 'Wed'){
if ($time >= 16 && $time <= 24 ) {
    $special = 'Wednesday Dinner Special';
}}



// Thu
if ($day == 'Thu'){ 
if ($time >= 0 && $time <= 11 ) {
    $special = 'Thursday Breakfast Special';
}}

if ($day == 'Thu'){ 
if ($time >= 11 && $time <= 16 ) {
    $special = 'Thursday Lunch Special';
}}

if ($day == 'Thu'){
if ($time >= 16 && $time <= 24 ) {
    $special = 'Thursday Dinner Special';
}}

// Fri
if ($day == 'Fri'){
if ($time >= 0 && $time <= 11 ) {
    $special = 'Friday Breakfast Special';
}}

if ($day == 'Fri'){
if ($time >= 11 && $time <= 16 ) {
    $special = 'Friday Lunch Special';
}}

if ($day == 'Fri'){
if ($time >= 16 && $time <= 24 ) {
    $special = 'Friday Dinner Special';
}}

// Sat
if ($day == 'Sat'){
if ($time >= 0 && $time <= 11 ) {
    $special = 'Saturday Breakfast Special';
}}

if ($day == 'Sat'){
if ($time >= 11 && $time <= 16 ) {
    $special = 'Saturday Lunch Special';
}}

if ($day == 'Sat'){
if ($time >= 16 && $time <= 24 ) {
    $special = 'Saturday Dinner Special';
}}

// Sun
if ($day == 'Sun'){
if ($time >= 0 && $time <= 11 ) {
    $special = 'Sunday Breakfast Special';
}}

if ($day == 'Sun'){
if ($time >= 11 && $time <= 16 ) {
    $special = 'Sunday Lunch Special';
}}

if ($day == 'Sun'){
if ($time >= 16 && $time <= 24 ) {
    $special = 'Sunday Dinner Special';
}}


echo $day;
echo ('<br /><br />');
echo $time;
echo ('<br /><br />');
echo $special;
?> 

 

I also had to change up the

$day =

to

$day ==

 

Thanks for the help.

Oh.  I missed the assignment operator misuse in your conditional test; shame on me!

 

Anyways you can always rewrite:

if( $c ) {
  if( $a && $b ) {
  }
}

 

as

 

if( $c && $a && $b ) {
}

 

They're logically equivalent.
