How to create var javascript via php ?
<?PHP
include("connect.php");
$get_data = mysqli_query($db_mysqli,"SELECT * FROM bad_word");
while($resilt_row = mysqli_fetch_array($get_data))
{
$bad_words = $bad_words."".$resilt_row [word].",";
}
//echo $bad_words;
?>
<script>
var bad_words = ["<?PHP echo $bad_words; ?>"];
alert(bad_words);
</script>
I want to get var javascript like this var bad_words = ["fuck", "ass"];
When alert it's get only blank result.
How can i do that ?
<?php
include("connect.php");
$query = mysqli_query($db_mysqli,"SELECT * FROM bad_word");
$badWords = [];
while($row = mysqli_fetch_array($query))
{
$badWords[] = $row['word'];
}
js
<script>
var bad_words = <?= json_encode($badWords); ?>;
alert(bad_words[0]);
console.log(bad_words);
</script>
I don't like gluing the strings if it's an array then pass it as an array with json_encode() function. Also in views it's better to use short syntax with <?= ?> tag
The string you're making is not the one you want.
You're not adding quotes.
Do this instead, using an array is better:
$get_data = mysqli_query($db_mysqli,"SELECT * FROM bad_word");
$bad_words = array();
while($resilt_row = mysqli_fetch_array($get_data))
{
$bad_words[] = "'" . $resilt_row[word]. "'";
}
And then, down in your js:
var bad_words = ["<?php echo implode(",", $bad_words) ?>"];
or (for short)
var bad_words = ["<?= implode(",", $bad_words) ?>"];
var bad_words = ["fuck,ass"]; not var bad_words = ["fuck", "ass"]; ?
var bad_words = ['first', 'second']If you want alert them as a string you can do it like this:
<script>
var bad_words = ["<?php echo implode('","',$bad_words); ?>"];
alert(bad_words);
</script>
Otherwise, you can print them as an array:
<script>
var bad_words = <?php echo json_encode($bad_words) ?>;
console.log(bad_words);
</script>
',' it must be '","'<?PHP
include("connect.php");
$get_data = mysqli_query($db_mysqli,"SELECT * FROM bad_word");
while($resilt_row = mysqli_fetch_array($get_data))
{
$bad_words[] = $resilt_row['word'];
}
//echo $bad_words;
?>
<script>
var bad_words = ["<?php print implode('","',$bad_words); ?>"];
alert(bad_words);
</script>
implode ?echoF.uck or F!uck .... neverending....
$bad_wordsvariable before thewhileblock$resilt_row [word]should be$resilt_row['word']?
