I am trying to pass both a string and an integer into the same function, howe I have issue with quotes. I figured out that the error is in the echo $q->info part, I must use double quotations on this code.
Can someone help me to write this $q->info, but to get real value not $q->info?
My code so far is
<td><a href="javascript:add(<?php echo $q->info?>,<?php echo $q->id?>)">Edit</a></td>
and the js function
function add(var,var2)
Can someone help me with this?
You have a PHP variable. To convert it to a string representation of a JavaScript literal, use json_encode. To make it safe to insert into an HTML attribute value, use htmlspecialchars.
<td><a href="javascript:add(<?php echo htmlspecialchars(json_encode($q->info)); ?>,<?php echo htmlspecialchars(json_encode($q->id)); ?>)">Edit</a></td>
That said, it would be better to write your code to follow the principles of Progressive Enhancement and Unobtrusive JavaScript.
<td>
<form action="edit" method="post">
<input type="hidden" name="info" value="<?php echo htmlspecialchars($q->info); ?>">
<input type="hidden" name="id" value="<?php echo htmlspecialchars($q->id); ?>">
<input type="submit" value="edit">
</form>
</td>
And then something like:
document.querySelector('form').addEventListener("submit", function (evt) {
evt.preventDefault();
add(this.elements.info.value, this.elements.id.value);
});
You need to quote the string.
<td><a href="javascript:add('<?php echo $q->info?>',<?php echo $q->id?>)">Edit</a></td>
Also, var is an invalid variable/argument name (identifier).
href="javascript:add(". That isn't going to work.' characters, no " characters and no new lines.Here is the answer of your question: Preg replace part of string?
echo substr($string, 0, strpos($string, "-DELETED"));
