Let me try and say this in a way that doesnt get anyone angry or confused.
I have a value that I am outputting into a table.
The value is populated by mysql and php.
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo "<table>";
echo "<tr>";
echo "<td id='countryDbId'>".$row['country']."</td>";
echo "</tr>";
echo "</table>";
}
$conn->close();
}
?>
Then I try to read all the values that were output with javascript.
<script>
var country = document.getElementById("pp").innerHTML;
console.log(country);
</script>
The output is only the first value even though there are over 100 values in that column.
Any help would be appreciated.
I am trying to make a SQL server table display pivoted in HTML using PHP.
The columns of the HTML table would be the content of the "CONCEPT" column of the SQL table and the content of the HTML columns would be the result of the "DATA" column of the SQL.
Not all records have the same number of "columns" that is, for example the serial number 12345 has the RAM column but the serial number 67890 does not, so the HTML table cell should appear as blank.
This is the tab delimited file: https://pastebin.com/sFJEHJLm
All the concepts of each article have a record with the same value as "LINE", but I don't know how to take advantage of this data to make the painting of the table.
I have tried to load each of the SQL columns in different PHP arrays and then cycle through the array by painting the HTML table but, at the moment a serial number that has a column arrives, the relationship of the results in the HTML table is lost With the correct column.
if ($_REQUEST['accion'] == "abrir_auditoria") {
$array_titulos = array();
$Total = 0;
$Actual = 0;
try
{
$sql = "SELECT * FROM AUDITORIAS_LIN WHERE AUDITORIA = '" . $_REQUEST['id'] . "'";
$q = $pdo->query($sql);
$q->setFetchMode(PDO::FETCH_ASSOC);
while ($r = $q->fetch()):
if (!in_array(htmlspecialchars($r['CONCEPTO']), $array_titulos))
{
array_push($array_titulos, htmlspecialchars($r['CONCEPTO']));
}
endwhile;
echo "<table border=1>";
echo "<tr>";
foreach ($array_titulos as $titulo)
{
echo "<th>$titulo</th>";
}
echo "</tr>";
echo "<tr>";
$q = $pdo->query($sql);
$q->setFetchMode(PDO::FETCH_ASSOC);
$Total = key(array_slice($array_titulos, -1, 1, true));
while ($r = $q->fetch()):
if ($Total != $Actual)
{
echo "<td>" . htmlspecialchars($r['DATO']) . "</td>";
$Actual++;
} else {
echo "</tr><tr>";
echo "<td>" . htmlspecialchars($r['DATO']) . "</td>";
$Actual = 0;
}
endwhile;
echo "</tr>";
echo "</table>";
}
catch(PDOException $pe)
{
die("database connect error：". $pe->getMessage());
}
}
I would like put my code to javascript var like that :
function myFunction(){
var switch = document..(etc..)....style.backgroundcolour;
var somethink2 = 'red'; <----- I tell about it
switch = somethink2;
}
and after that my background colour will be switch after using function.
I can"t do that with PHP code (my code connection with sql database) becouse i have not got a " and '.
"dane" (in getElementByID()) in my code below is and i want put this PHP code inside this div.
Guys please help me :)
Regards!
function swap(){
var zawartosc =
<?php $a4="SELECT silnik FROM marki WHERE model = 'A4'";
$result2 = mysqli_query($connection,$a4);
echo "<br>";
echo "<table border='1'>"; // I WANT PUT THIS LIKE A TEXT
while ($row = mysqli_fetch_assoc($result2)) {
echo "<tr>";
foreach ($row as $field => $value) {
echo "<td>" . $value . "</td>";
}
echo "</tr>";
}
echo "</table>";
?>
document.getElementById("dane").innerHTML = zawartosc;
}
Something like this:
$a4="SELECT silnik FROM marki WHERE model = 'A4'";
$result2 = mysqli_query($connection,$a4);
$html = [];
$html[] = "<br>";
$html[] = "<table border='1'>"; // I WANT PUT THIS LIKE A TEXT
while ($row = mysqli_fetch_assoc($result2)) {
$html[] = "<tr>";
foreach ($row as $field => $value) {
$html[] = "<td>" . $value . "</td>";
}
$html[] = "</tr>";
}
$html[] = "</table>";
$html = json_encode($html); //'["<br>","<table border='1'>", ...]'
?>
document.getElementById("dane").innerHTML = <?php echo $html;?>.join("\n"); //no quotes needed
//document.getElementById("dane").innerHTML = ["<br>","<table border='1'>", ...].join("\n");
Or you can just handle it like a normal string, but it's not what I would prefer to do.
$html = implode($html);
?>
document.getElementById("dane").innerHTML = "<?php echo $html;?>"; //careful with quotes here
In other words, don't output from PHP directly, instead build an array. It's much cleaner as you can consolidate that into a single variable and then use it.
For example:
//timeout for demonstration purposes
setTimeout(function(){
document.getElementById("dane").innerHTML = [
"<br>",
"<table border='1'>",
"<tr>",
"<td>foo</td>",
"<td>bar</td>",
"</tr>",
"<tr>",
"<td>biz</td>",
"<td>baz</td>",
"</tr>",
"</table>"
].join("\n");
},500);
table{width:100px;}
<div id="dane"></div>
I like using join (it's like implode) for multi line strings in JS (even in my plugins). In this case it works well with json_encode.
Basically we convert that array of HTML into a JSON string, which becomes a real Array in JS, then we let JS do the imploding with join. Mainly because arrays don't require the use of a quote, so this avoids any issues if we have quotes in our html.
Consider this (using just strings):
<?php
//HEREDOC
$html = <<<HTML
<table border='1' style="color:red;" >
HTML;
?>
document.getElementById("dane").innerHTML = '<?php echo $html;?>';
document.getElementById("dane").innerHTML = "<?php echo $html;?>";
Which becomes this:
document.getElementById("dane").innerHTML = '<table border='1' style="color:red;">'; //syntax error
document.getElementById("dane").innerHTML = "<table border='1' style="color:red;">"; //syntax error
From what I see you can get away with " at the moment, but if you put them in your HTML, you'll probably be in trouble (if your just using strings). Using join avoids this
document.getElementById("dane").innerHTML = ["<table border='1' style=\"color:red;\">"].join("\n"); //json_encode knows how to escape " for json.
Hope it helps!
I have a problem, trying to create a button with Ajax/Php which is to appear on my main page and is supposed to have a onclick function. To be more specific, I end up in a while loop, which fetches through the rows of my mySQL-table and displays the following:
echo "<table>";
while($result == true && $a <= 15){
$res = $result["uberschrift"];
echo "<tr id='$res'>";
echo "<td>".$a."</td>";
echo "<td>".$res."</td>";
echo "<td>"."<button id='b_löschen' onclick='k_löschen($res)'> löschen </button>"."</td>";
echo "</tr>";
$result = $stmt->fetch();
$a++;
}
echo "</table>";
In fact, this works quite well, and on my main page the string contained in $result["uberschrift"] is displayed properly. However, if I call the function k_löschen with $res as shown above, it will not take the String but a certain
[object HTMLTablerowElement] as input, which naturally causes an Error. Can someone tell me how to change the code so that the function actually takes the string as it's input?
You have issues with your quotes. Also you could tell us what $res typically contained.
I would do this
echo "<tr id=\"".$res."\">";
echo "<td><button id='b_löschen' onclick='k_löschen(\"".$res."\")'>löschen</button></td>";
My 1 file is city.html which contains the following code
<script language="javascript">alert("Page Called"); </script>
'Bhubaneshwar', 'Orissa', 'India'
My another file index.php contains the following code
$x=file_get_contents("city.html");
$x=array($x);
echo $x[0];
It shows the following output
'Bhubaneshwar', 'Orissa', 'India'
But I want single word output like this.
When I print $x[0], it should be Bhubaneshwar
When I print $x[1], it should be Orissa
When I print $x[2], it should be India
First you need to remove script tags
$x = file_get_contents("city.html");
$x = preg_replace('%<script[^>]*>.*?</script>%/m', '', $x);
and then you can use explode:
$array = explode(',', $x);
then you can trim and remove quotes:
$array = array_map(function($item) {
return preg_replace("/^'|'$/", trim($item));
}, $array);
Use explode to convert string to array:-
// Remove script tag
$string = preg_replace('#<script(.*?)>(.*?)</script>#is', '', $x);
// $string = str_replace(' ', '', $string); // Remove space from string
$string = preg_replace('/\s+/', '', $string); // Remove whitespace from string
// explode string
$x = explode(',',$string);
Hope it will help you :)
Try,
$x=file_get_contents("city.html");
$x=array($x);
$html = preg_replace('#<script[^>]*?.*?</script>#', '', $x);
$str = str_replace(', ', ',', $html);
$x = explode(',',trim($str[0]));
$remove[] = "'";
$result = str_replace( $remove, "", $x );
foreach($result as $cities)
{
echo $cities . "<br>";
}
Here is code that first removes the preceding script tag(s) and breaks down the remainder into an array:
$x=array_pop(explode('</script>', $x));
$x=preg_split("/'\s*,\s*'/", trim(trim($x), "'"));
The first of those two statements is only needed if you keep that script tag inside your HTML, which seems to be there for testing only.
To display the result, you could do this:
foreach($x as $item) {
echo $item . "<br>";
}
Output:
Bhubaneshwar
Orissa
India
Considerations
It is unusual to have such data format inside HTML files. HTML is intended for rendering data in a user-friendly manner, and that representation does not really fit.
If you are the creator of the HTML file, then consider moving to a JSON format. In that case your file would be named city.json and would have this content (the double quotes and brackets are required):
["Bhubaneshwar", "Orissa", "India"]
And the code would make use of JSON functions like this:
$json=file_get_contents("city.json");
$x=json_decode($json);
This way you really use standards, and the code is compact.
You could again display the contents of $x like before:
foreach($x as $item) {
echo $item . "<br>";
}
Output:
Bhubaneshwar
Orissa
India
If you are the creator of that file, and use PHP to create it, then make use of JSON functions as well, as follows:
$x = array("Bhubaneshwar", "Orissa", "India");
file_put_contents ("city.json", json_encode($x));
