<?php echo '<form action="hwCase.php" method="post"> Enter number <input type="text" name="number"/><br /> </form>'; $input = $_POST['number']; // if a number is entered in the form, ie not null if (isset($input)) { switch ($input) { // if number entered is less than 0, ie negative number case ($input<0): echo "Enter a positive number."; break; // if number entered is greater than 1000 case ($input>1000): echo "Enter a number less than 1000."; break; // if number entered is not a number, ie a letter, a character case (!ctype_digit($input)): echo "<br><img src=\"squidward.jpg\"><br><br>Enter a valid number. "; break; // if valid number is entered, loop "hello world" that many times case (($input>0) && ($input<1000)): echo "hello world " . $input . "<br />"; break; // if anything else is entered default: echo "Enter a number."; break; } } // if no number is entered in the form, ie null else { echo "Please enter a number."; } ?> For some reason, my loop doesn't work. Please help me fix it! Thanks in advance! I need to loop this part: case (($input>0) && ($input<1000)): echo "hello world " . $input . "<br />"; break;

Hello again. I need help for a PHP project I'm working on for school. I need it to do the following: 1) When nothing is entered, it will echo "Please enter a number." 2) When "0" is entered, it will echo "Please enter a number that is not zero." My code is as follows... <form action="hwpositive.php" method="post"> Enter number <input type="text" name="number"/><br /> </form> <?php $input = $_POST['number']; // if number entered is less than 0 if ($input<0) { echo "Enter a positive number."; } // if number entered is greated than 1000 elseif ($input>1000) { echo "Enter a number less than 1000."; } // if number entered is not a number (ie, a letter, a character) elseif (!is_numeric($input)) { echo "<br><img src=\"squidward.jpg\"><br><br>Enter a valid number. "; } // if number entered is between 1-999 elseif (($input>0) && ($input<1000)) { echo "hello world " . $i . "<br />"; } // if number entered is zero elseif ($input===0) { echo "Please enter a number that is not zero."; } // if no number is entered elseif ($input=null) { echo "Please enter a number."; } else { echo "Please enter a number."; } ?> However, it's not working. What am I doing wrong? Everytime I enter this page, it should show me "Please enter a number" because I haven't entered anything yet, but it doesn't. It's showing me the image right away. I don't understand... Help me, please! Thank you so much in advance. I appreciate the help.

Thank you for your help! The code you provided works.

Hi, everyone. I need help with a PHP project on which I'm currently working. I need to create a form which does the following: 1) When you insert a negative number, it echoes: "Please insert a positive number." 2) When you insert a number greater than 1000, it echoes: "Please insert a number less than 1000." 3) When you insert anything else that's not a number (ie: a letter), it echoes: "Please insert a valid number." 4) If it doesn't do any of the above, it'll take the number that you entered and loop "Hello World" as many times as that number. The code that I have so far looks something like below. (I had to type it from the top of my head.) <?php <form action="hwpositive.php" method="post"> Enter number: <input type="text" name="number" /> </form> $input = $_POST["number"]; if ($input<0) { echo "Please insert a positive number."; } else if ($input>1000) { echo "Please insert a number less than 1000."; } else if ($input!=is_numeric) { echo "Please insert a valid number."; } else { for {$i; $i<=$_POST["number"]; $i++;} } ?> I can get this code to do the first three tasks listed above, but not the last. I'm a high school Programming 12 student, and this is my first year of learning PHP coding. Please help me out. Would it be better to use the case-switch option? I'm not too familiar on how to use it. Thank you in advance! I appreciate your help greatly.
