Looking for a more neat solution to returning specific rows from a repeater

Hi,

I have a repeater field from which I need to return values from specific rows to different locations in my markup. I got my code to work, but I don’t believe it’s a neat solution, and was looking for something better.

This is was I currently have:

<?php
  $stripTagExcept = '<br> <strong> <em> <u> <del> <a> <img> <ul> <ol> <li> <span> <blockquote>';
  if( have_rows('home_steps_steps', 2) ) {
    while( have_rows('home_steps_steps', 2) ) { the_row();
      if( get_sub_field('home_steps_steps_id') == 1 ) {
        $stepIconOne = get_sub_field('home_steps_steps_icon');
        $stepTitleOne = get_sub_field('home_steps_steps_title');
        $stepParagraphOne = get_sub_field('home_steps_steps_paragraph');
        $stepPOneFormat = strip_tags($stepParagraphOne, $stripTagExcept);
      }
      if( get_sub_field('home_steps_steps_id') == 2 ) {
        $stepIconTwo = get_sub_field('home_steps_steps_icon');
        $stepTitleTwo = get_sub_field('home_steps_steps_title');
        $stepParagraphTwo = get_sub_field('home_steps_steps_paragraph');
        $stepPTwoFormat = strip_tags($stepParagraphTwo, $stripTagExcept);
      }
      if( get_sub_field('home_steps_steps_id') == 3 ) {
        $stepIconThree = get_sub_field('home_steps_steps_icon');
        $stepTitleThree = get_sub_field('home_steps_steps_title');
        $stepParagraphThree = get_sub_field('home_steps_steps_paragraph');
        $stepPThreeFormat = strip_tags($stepParagraphThree, $stripTagExcept);
      }
      if( get_sub_field('home_steps_steps_id') == 4 ) {
        $stepIconFour = get_sub_field('home_steps_steps_icon');
        $stepTitleFour = get_sub_field('home_steps_steps_title');
        $stepParagraphFour = get_sub_field('home_steps_steps_paragraph');
        $stepPFourFormat = strip_tags($stepParagraphFour, $stripTagExcept);
      }
      if( get_sub_field('home_steps_steps_id') == 5 ) {
        $stepIconFive = get_sub_field('home_steps_steps_icon');
        $stepTitleFive = get_sub_field('home_steps_steps_title');
        $stepParagraphFive = get_sub_field('home_steps_steps_paragraph');
        $stepPFiveFormat = strip_tags($stepParagraphFive, $stripTagExcept);
      }
    }
  }
?>

I basically added an addition field in which I added a unique ID (1-5 for now) and use this field to return the values in a variable.

Is there a neater way to do this? I have only been working with PHP for the last 2 months, so I wouldn’t know of anything better at the moment. I also looked up the ACF documentation, but it didn’t get me really far for once. Thanks in advance!

I would use a switch statement, they are cleaner when you have many possiblities

$steps = get_sub_field('home_steps_steps_id');
switch ($steps) {
  case 1:
    // do something
    break;
  case 2:
    // do something
    break;
  case 3:
    // do something
    break;
  case 4:
    // do something
    break;
  case 5:
    // do something
    break;
}

Thanks John! I am going to try this.
