A PHP if () between two numbers

[chadrt]

Ok here goes this little experiment...

if (($coumadinEntry->inr >= 2) && ($coumadinEntry->inr <= 3)) {
$coumadinINR = $coumadinEntry->inr." It's Good";
}else{
$coumadinINR = $coumadinEntry->inr." Adjustment Needed";
}

this is located in a "foreach" building a table and although "It's Good" works reliably it now fills every box in that column with "Adjustment Needed" unless that column is between 2 and 3.

 

What I am wanting to happen is:

• If between 2 and 3 it shows the level INR and "It's Good"
• If below 2 it will show something else (likely "actual reading and an icon of some sort on each side of the number)
• If above 3 it show something else (likely "actual reading and an icon of some sort on each side of the number)
• if empty or NULL then it will set $coumadinINR=""; so nothing is displayed

Okay... so... do that? You already seem to understand how comparisons work so write a couple more of them.

[chadrt]

if (($coumadinEntry->inr >= 2) && ($coumadinEntry->inr <= 3)) {
$coumadinINR = $coumadinEntry->inr." It's Good";
}elseif($coumadinEntry->inr < 2){
$coumadinINR = $coumadinEntry->inr." It's Low";
}elseif($coumadinEntry->inr > 3){
$coumadinINR = $coumadinEntry->inr." It's High";
}else{
$coumadinINR = "";
}

Ok so there is my hundredth attempt at this.

 

I know why its failing but I don't how to correct for it.  At this point because NULL is less than 2 it assumes that this is true and displays the "It's Low" with no value.

 

I thought this was the answer but I am missing something.  I

if (($coumadinEntry->inr >= 2) && ($coumadinEntry->inr <= 3)) {
$coumadinINR = $coumadinEntry->inr." It's Good";
}elseif($coumadinEntry->inr < 2) && ($coumadinEntry->inr != ''){
$coumadinINR = $coumadinEntry->inr." It's Low";
}elseif($coumadinEntry->inr > 3){
$coumadinINR = $coumadinEntry->inr." It's High";
}else{
$coumadinINR = "";
}

I think I am on the right track but its kicking me still...

if (($coumadinEntry->inr >= 2) && ($coumadinEntry->inr <= 3)) {
$coumadinINR = $coumadinEntry->inr." It's Good";
}elseif(is_null($coumadinEntry->inr)){
coumadinINR = "";
}elseif($coumadinEntry->inr < 2){
$coumadinINR = $coumadinEntry->inr." It's Low";
}elseif($coumadinEntry->inr > 3){
$coumadinINR = $coumadinEntry->inr." It's High";
}else{};

oh my brain hurts now, us amateurs should be banned from any kind of code

if (($coumadinEntry->inr >= 2) && ($coumadinEntry->inr <= 3)) {
$coumadinINR = $coumadinEntry->inr." It's Good";
}

elseif(is_null($coumadinEntry->inr)){
$coumadinINR = "";
}

elseif($coumadinEntry->inr < 2){
$coumadinINR = $coumadinEntry->inr." It's Low";
}

elseif($coumadinEntry->inr > 3){
$coumadinINR = $coumadinEntry->inr." It's High";
}else{}

But alas its done and it works...

if ($coumadinEntry->inr === null){

    $coumadinINR = "";

} else if ($coumadinEntry->inr < 2){

    $coumadinINR = $coumadinEntry->inr." It's Low";

} else if ($coumadinEntry->inr > 3){

    $coumadinINR = $coumadinEntry->inr." It's High";

} else {

    $coumadinINR = $coumadinEntry->inr." It's Good";

}

Start with your null condition so it doesn't get mixed up with the < 2 condition. Then check your less than or higher than conditions. If those all fail then it must be 2 or 3.
