Skip row if more than one cell is empty with PHP - php

Question

I have a PHP script that generates an HTML table from a CSV file.
Right now if any cells are missing information, it skips the row. HOWEVER, I'd prefer if it skipped a row if more than one cell was missing. So if a row has 2 empty cells, it should skip.
I have marked it //edit here below but unsure how to acheive this.
<?php
$idsColumnsWanted = array(0,1,8,19);
echo "<table class='table table-bordered' id='example'>\n\n";
$f = fopen("users.csv", "r");
$first_line = false;
while (($line = fgetcsv($f)) !== false) {
// Restart column index
$i = 0;
$row ="";
if($first_line == false) {
$row = "<thead><tr>";
$col = "th";
} else {
$row = "<tr>";
$col= "td";
}
$is_empty = false;
foreach ($line as $i => $cell) {
// Skips all columns not in your list
if (! in_array($i, $idsColumnsWanted)) continue;
// edit here
if ($cell !== '') {
$row .= "<".$col.">" . htmlspecialchars($cell) . " </".$col.">";
} else {
$is_empty = true;
}
// Increase index
$i++;
}
if($first_line == false)
$row .= "</tr></thead>";
else
$row .= "</tr>";
$first_line = true;
if ($is_empty) {
continue;
} else {
echo $row;
}
}
fclose($f);
echo "\n</table>";
?>

Answer 1

please try this code
$is_empty = false;
$count = 0;
$countlimit = 2; // define empty cell limit here
foreach ($line as $i => $cell) {
// Skips all columns not in your list
if (!in_array($i, $idsColumnsWanted))
continue;
// edit here
if($cell==""){
$count++;
}
if ($count <= $countlimit) {
$row .= "<" . $col . ">" . htmlspecialchars($cell) . " </" . $col . ">";
} else {
$is_empty = true;
break;
}
}

You have to cound how many cells are empty in a row. To do so init the counter for each line.
$empty_cells = 0; //Init with 0 for each line
foreach ($line as $i => $cell) {
// Skips all columns not in your list
if (! in_array($i, $idsColumnsWanted)) continue;
// edit here
if ($cell !== '') {
$row .= "<".$col.">" . htmlspecialchars($cell) . " </".$col.">";
} else {
$empty_cells++; //count how many empty cells you have.
}
// Increase index
$i++;
}
and after that check if there are more than two empty cells like this:
if ($empty_cells >= 2) {
continue;
} else {
echo $row;
}
