Question

I have a PHP code which I am using to display the list of comments from my database to the webpage.

CODE-

while ($row = mysqli_fetch_assoc($query)) { // Loop through results of query

  if ($row['depth'] > $cur_depth) {
   if($row['depth'] == 1){
   echo "<ul>\n";
    runthis();
    $cur_depth = $row['depth'];
   }
    else   if($row['depth'] == 2){
      echo "<ul class='selected'>\n";
      runthat();
      $cur_depth = $row['depth'];
    }
    else{
    echo "<ul>\n";
    runthats();
    $cur_depth = $row['depth'];
    }
  }
  else while ($cur_depth > $row['depth']) {
    echo "</ul>\n";
    $cur_depth--;
  }
  function runthis(){
  echo "<li id=" .$row['depth'] . " class='some_class'>" . $row['comment'] . " &nbsp;id-". $row['category_id'] ."<a href='' id='toggle-cm'>reply</a><br/><div id='commentarea'><textarea row=5 cols=40>write something here...</textarea><br/><button id=" . $row['category_id'] . ">reply to this comment</button></div></li>\n";
  }

  function runthat(){
  echo "<li id=" .$row['depth'] . ">" . $row['comment'] . " &nbsp;id-". $row['category_id'] ."<a href='' id='toggle-cm'>reply</a><br/><div id='commentarea'><textarea row=5 cols=40>write something here...</textarea><br/><button id=" . $row['category_id'] . ">reply to this comment</button></div></li>\n";
  }
}
while ($cur_depth > -1) {
  echo "</ul>\n";
  $cur_depth--;
}

What it does is fetch the comments from the sql database and displays it in hierarchical manner. $row['depth'] is variable that stores the depth of the comment. Now, I want to add class some_class to the <li> elements the has row['depth'] = 1 and also assign some property to <ul> element that has row['depth'] = 2.

Original code was working fine but I modified it a bit to assign classes and properties.

ORIGINAL CODE-

while ($row = mysqli_fetch_assoc($query)) { // Loop through results of query
  if ($row['depth'] > $cur_depth) {
    echo "<ul>\n";
    $cur_depth = $row['depth'];
  }
  else while ($cur_depth > $row['depth']) {
    echo "</ul>\n";
    $cur_depth--;
  }
  echo "<li>" . $row['comment'] . "id-". $row['category_id'] ."<a href='' id='toggle-cm'>reply</a><br/><div id='commentarea'><textarea row=5 cols=40>write something here...</textarea><br/><button id=" . $row['category_id'] . ">reply to this comment</button></div></li>\n";
}
while ($cur_depth > -1) {
  echo "</ul>\n";
  $cur_depth--;
}

Now, what I want to achieve is to make some changes in this original code, so that some different property is assigned to <li> element that has row['depth'] = 1 and some different property is applied to the <ul> element that has depth 2. I am getting error using the modified code I shown.

ERROR-

Fatal error: Call to undefined function runthat()

Where am I wrong?

Answer 1

replace:

runthats();

by

runthat();

and do not use the function in a while
