[SOLVED] How do I make my if statement true or false?

[pneudralics]

I want to be able to check my nested if statements to see if it's true or false. How would I write that?

 

EXAMPLE

if (this is true and the 2nd if is true){
}
else {
}
if (the first if is true){
}
else {
do this if the first is not true
}

Just like your pseudo code:

<?php
if ($first && $second) {
   echo 'Both $first & $second are true<br>';
} else {
   if ($first) {
       echo '$first is true, but second is false<br>';
   } else {
       echo 'Both $first & $second are false<br>';
   }
}
?>

Is there a way to assign an if statement to some kind of variable?

[kenrbnsn]

What do you mean? Please explain.

if ($first=="abc" && $second=="efg") {
   echo 'Both $first & $second are true
';
   } else {
   if ($first=="abc") {
      echo '$first is true, but second is false
';
   } else {
      echo 'Both $first & $second are false
';
   }
}

i think he is talking about getting a return from the if statement as you can do with functions. if that is the case why would you want to do that?

There are many reasons why you would want to do that.  First of all you should have a variable for the return.  Something like:

 

function getNumber($first, $second) 
{
if ($first=="abc" && $second=="efg") {
   echo 'Both $first & $second are true
';
   return 1;
   } else {
   if ($first=="abc") {
      echo '$first is true, but second is false
';
   return 4;
   } else {
      echo 'Both $first & $second are false
';
      return 3;
   }
}
}

from what i am understanding i think he wants to be able to right an if inside an if(if(blah<blah){return 1;}){echo "yeah";}

Until the OP explains what he wants, we're all just guessing.

kenrbnsn is right, we're all wasting our time guessing as to what the OP exactly wants.

huh?

"Is there a way to assign an if statement to some kind of variable?"

 

now that is what makes me believe he wants a return from his if statements (but not have the if in a function)

that could be done like so

 

if(a < b)

{

  $AA = 1;

}

else

{

  $AA = 0;

}

Sorry I was kind of busy and didn't have time to respond. I'm trying to write a code for uploading an image and thumbnail. I tried nesting bunch of if statements but I can't seem to get it to work.

 

I want to have it where if the thumbnail image doesn't upload I don't want the main image to upload either vice versa. I'm trying to see if I can make an if statement true or false so it can check it before it uploads. My problem is I can't get the thumbnail to check to not upload if the main does not upload. When I nested it and the main image uploads it go on to the next if which is the thumbnail image and it won't be able to check anymore since it's already completed.

 

//Set main image, thumbnail and writing image name to database to true
$mainimagecheck = true;
$thumbnailimagecheck = true;
$databaseimagecheck = true;

//Check for main image
if ($thumbnailimagecheck = true) {
if ($mainimagecheck) {
	if (move_uploaded_file ($_FILES['image']['tmp_name'], GALLERYUPLOAD."$newname2")) {
		echo '<font color="red">Main image uploaded successfully.</font><br />';
	} 
} else {
	echo '<font color="red">Problem uploading main image.</font><br />';
}
} else {
echo '<font color="red">Main image didn\'t upload because thumbnail image didn\'t upload.</font><br />';
exit (); 
}
//Check for thumbnail image
if ($mainimagecheck = true) {
if ($thumbnailimagecheck) {
	if (move_uploaded_file ($_FILES['timage']['tmp_name'], GALLERYTHUMBNAILUPLOAD."$newname2")) {
		echo '<font color="red">Thumbnail image uploaded successfully.</font><br />';
	} 
} else {
	echo '<font color="red">Problem uploading thumbnail image.</font><br />';
}
} else {
echo '<font color="red">Thumbnail image didn\'t upload because main image didn\'t upload.</font><br />';
exit ();
}
//End image upload
//If inputs empty do not load the database
if ($mainimagecheck && $thumbnailimagecheck) {
if	(mysql_query("INSERT INTO gallery (image) VALUE ('$newname2')")) {
	echo '<font color="red">The images have been written to the database successfully.</font><br /><br />';
} else {
	echo '<font color="red">Images did not write to the database.</font><br /><br />';
}
} else {
echo '<font color="red">Images did not write to the database because main or thumbnail didn\'t upload.</font><br /><br />';
exit ();
}

what error you getting with the script because just having a quick skim though it and it seems alrite

[kenrbnsn]

This statement

<?php
if ($thumbnailimagecheck = true) {
?>

should be either

<?php
if ($thumbnailimagecheck == true) {
?>

or

<?php
if ($thumbnailimagecheck) {
?>

 

Use one "=" for assignment and two "==" for comparison.
