I'm trying to generate auto description from tags.
The code was working but after updating my site to Laravel 6 in stop working. I need to get it back working.
if( !empty( $request->description ) )
{
$description = Helper::checkTextDb($request->description);
}
else
{
$a_key = explode(",", strtolower($request->tags));
if(count($a_key) == 0)
$description = 'This is a great thing';
else
{
$description_get_keys = '';
foreach ($a_key as &$value)
{
if($value == end($a_key) && count($a_key) != 1)
$description_get_keys = $description_get_keys.' and '.$value.'.';
else if(count($a_key) == 1)
$description_get_keys = $value.'.';
else if (count($a_key) > 1 && $a_key[0] == $value)
$description_get_keys = $value;
else
$description_get_keys = $description_get_keys.', '.$value;
}
$description = 'This is a great thing about '.$description_get_keys;
}
}
I see a couple things that could possibly be an issue, not knowing what came before this code.
I will assume that the $request variable is an instance of Illuminate\Http\Request and that it is available in the function, right?
Try this updated code:
if($request->has('description'))
{
$description = Helper::checkTextDb($request->description);
}
else if ($request->has('tags'))
{
if (strpos($request->tags, ',') === false)
{
$description = 'This is a great thing';
}
else {
$a_key = explode(",", strtolower($request->tags));
$a_count = count($a_key);
$description_get_keys = '';
for ($i = 0; $i < $a_count; $i++)
{
if ($a_count == 1) {
$description_get_keys = "{$a_key[$i]}.";
}
else {
// first
if ($i === 0) {
$description_get_keys = $a_key[0];
}
// last
else if ($i === $a_count - 1) {
$description_get_keys .= " and {$a_key[$i]}.";
}
// middle
else {
$description_get_keys .= ", {$a_key[$i]}";
}
}
}
$description = "This is a great thing about {$description_get_keys}";
}
}
I wrote that quick so hopefully there are no errors.
I've a question for you if you can help me, I've some variables that I retrieve with them data from database, but I want to resolve this problem
if all the variables are empty then show something if not then show the just the variables that have data.
The Code is:
foreach ($row as $result) {
if ($row[29] == '') {
$string29 = '';
}else if ($row[29] == 0){
$string29 = '';
} else{
$string29 = '<div class="add_img"><h1>Pression</h1><img src="images/'.$row[29].'.png"></div>';
}
}
foreach ($row as $result) {
if ($row[30] == '') {
$string30 = '';
}else if($row[30] == 0){
$string30 = '';
} else{
$string30 = '<div class="add_img"><h1>Fixation</h1><img src="images/'.$row[30].'.png"></div>';
}
}
`
Then I have
echo &string29 and so on........
Your code is rather redundant. By PHP typecasting rules, 0 and '' are actually loosely equal:
php > var_dump(0 == '');
bool(true)
What you should be doing is have an array of keys/names you could loop over, e.g:
$fields = array(29 => 'Pression', 30 => 'Fixation');
foreach ($fields as $key => $field) {
if ($row[$key]) { .... }
echo '...';
}
hey guys im trying to get the even indexes of a string from the db then save them in a variable then echo. but my codes seems doesnt work. please help. here it is
require_once('DBconnect.php');
$school_id = '1';
$section_id = '39';
$select_pk = "SELECT * FROM section
WHERE school_id = '$school_id'
AND section_id = '$section_id'";
$query = mysql_query($select_pk) or die (mysql_error());
while ($row = mysql_fetch_assoc($query)) {
$public_key = $row['public_key'];
}
if ($public_key) {
$leng_public_key = strlen($public_key);
$priv_key_extract = "";
$array_pki = array();
for ($i=0; $i <=$leng_public_key-1 ; $i++) {
array_push($array_pki,$public_key[$i]);
}
foreach ($array_pki as $key => $value) {
if($key % 2 == 0) {
$priv_key_extract += $public_key[$key];
} else {
$priv_key_extract ="haiiizzz";
}
}
}
echo $priv_key_extract;
as you can see im trying to use modulo 2 to see if the index is even.
I have updated your code as below, it will work now :
<?php
$public_key = 'A0L8V1I5N9';
if ($public_key) {
$leng_public_key = strlen($public_key);
$priv_key_extract = "";
$array_pki = array();
for ($i=0; $i <=$leng_public_key-1 ; $i++) {
array_push($array_pki,$public_key[$i]);
}
foreach ($array_pki as $key => $value) {
//Changed condition below $key % 2 ==0 => replaced with $key % 2 == 1
if($key % 2 == 1) {
// Changed concatenation operator , += replaced with .=
$priv_key_extract .= $public_key[$key];
} /*else {
//Commented this as it is getting overwritten
$priv_key_extract ="haiiizzz";
}*/
}
}
echo $priv_key_extract;
?>
Try this function
function extractKey($key) {
if (empty($key) || !is_string($key)) return '';
$pkey = '';
for ($i=0;$i<strlen($key);$i++) {
if ($i % 2 == 0) {
$pkey .= $key[$i];
}
}
return $pkey;
}
echo extractKey('12345678'); # => 1357
This code works perfectly except that it doesn't print the last 2 rows of my csv file:
This is the file:
603629,0,ATLV0008,"Vendor1",1942.60,11/04/2010,1942.60,9/1-9/30/10,EFT-JP
603627,2,ATLV0008,"Vendor1",1242.40,11/04/2010,1242.40,7/1-7/31/10,EFT-JP
600023,0,FLD4V0003,"Vendor2",1950.00,06/15/2010,1950.00,6/14/10 Request,EFT-JP
600024,0,FLD4V0003,"Vendor2",1800.00,06/15/2010,1800.00,6/14/10 Request,EFT-JP

603653,0,ATLV0403,"Vendor4",931.21,11/17/2010,931.21,9/1-9/30/10,EFT-JP
603661,0,ATLV0105,"Vendor5",26.75,11/19/2010,26.75,093139,PM2
603660,1,ATLV0105,"Vendor5",5.35,11/19/2010,5.35,093472,PM2
Here is the code: (It needs to display the sum of 2 rows with the same vendor before the actual rows)
if (($handle = fopen('upload/ATLANTA.csv', "r")) !== FALSE) {
while (($row_array = fgetcsv($handle, 1000, ","))) {
foreach ($row_array as $key => $val) {
$row_array[$key] = trim(str_replace('"', '', $val));
ob_flush();
}
$complete[] = $row_array;
ob_flush();
}
}
flush();
$prevVendor = '';
$sum = 0;
$venData = '';
if (isset($complete)) {
foreach ($complete as $key => $val) {
$venData .= "<br/>";
$currVendor = $complete[$key][3];
if ($currVendor != $prevVendor){
if ($prevVendor != NULL){
print "<br/>";
print $sum . "<br/>";
print $venData;
$sum = 0; $venData = '';
}
}
foreach ($val as $ikey => $ival){
if ($ikey != 1){
$venData .= $ival . ' ';
$prevVendor = $val[3];
}
}
if ($currVendor == $prevVendor){
$sum += $complete[$key][6];
}
}
}
I don't really understand your problem but if you want to get (and save it wherever you want) the sum of each vendors, you should do something like this :
$prevVendor = null;
$venData = '';
$sums = array();
if (isset($complete) && is_array($complete)) {
$lim = count($complete);
for ($key=0;$key<$lim;++$key) { // no need foreach for simple array
$venData .= "<br/>";
$currVendor = $complete[$key][3];
if ($currVendor != $prevVendor){
if ($prevVendor != null){
print "<br/>";
print $venData;
}
$venData = '';
$prevVendor = $currVendor;
$sums[$currVendor] = 0; // set the counter to 0
}
foreach ($complete[$key] as $ikey => $ival){
if ($ikey != 1){
$venData .= $ival . ' '; // is useful for you I guess
}
}
$sums[$currVendor] += $complete[$key][6]; // add amounts
}
}
if ($prevVendor != null){ // you need to do this to display the last record
print "<br/>";
print $venData;
}
var_export($sums); // check results
This can be some syntax errors ...
I have an array which i do a foreach($array as $key => $value)
in my $key i get
name[1][1]
name[1][2]
name[1][3]
name[2][1]
name[2][2]
how can I add detect when the first index changes from [1][3]->[2][1]
any help is appreciated.
What i want to achieve is this:
<h4>Header</h4>
name[1][1]
name[1][2]
name[1][3]
<h4>Header</h4>
name[2][1]
name[2][2]
<h4>Header</h4>
name[3][1]
name[3][2]
name[3][3]
name[3][4]
Don't know if it is the best option, but this is how i managed to do it.
<?php $k = 1; $flag1 = 0; $flag2 = 1;foreach ($this->cart->product_options($items['rowid']) as $option_name => $option_value): ?>
<?php
$endpos = strpos($option_name,']');
$asd = substr($option_name,5,$endpos-5);
$this->firephp->log($asd);
if($asd % 2)
{
if($flag1 === 0)
{
echo ' <h4>Header '. $k .'</h4>';
$flag1 = 1;
$flag2 = 0;
$k++;
}
}
else
{
if($flag2 === 0)
{
echo ' <h4>Header '. $k. '</h4>';
$flag2 = 1;
$flag1 = 0;
$k++;
}
}
?>
You can try like
foreach($name as $parent_key => $parent_value){
echo "<h4>Header</h4><br/>";
foreach($name[$parent_key] as $key=>$value)
{
echo $name[$i][$key]."<br/>";
}
}
foreach($array as $key => $value){
$valuevalues = array();
foreach($value as $val){
if($val != "" && !isset($valuevalues[$key][$val]))
$valuevalues[$key][$val] = "different-than-previous";
if(!isset($valuevalues[$key][$val]))
$valuevalues[$key][$val] = "equal-to-first-value";
}
}
