How can i remove "dato" from $this->v ? And still have it in the $sql string.
OUTPUT (var_dump($this->v)):
array (size=4)
':kategori' => string 'Youstube' (length=8)
':link' => string 'http://urls' (length=11)
':navn' => string 'Rss feeds' (length=9)
':dato' => string 'NOW()' (length=5)
OUTPUT (echo $sql)
UPDATE rss_kategori SET kategori = :kategori, link = :link, navn = :navn, dato = NOW()
CODE:
$classVars = get_class_vars(get_class($this));
$sql .= "UPDATE {$this->table} SET ";
foreach ($classVars as $key => $value) {
if ($key == 'v' || $key == 'db' || $key == 'id' || $key == 'table' || $key ==
'table_id') {
continue;
}
$keys = "";
$values = "";
$keys .= $key;
if ($this->$key == 'NOW()') {
$values .= $this->$key . ",";
} else {
$values .= ":" . $key . ",";
}
$this->v[":" . $key] = $this->$key;
$sql .= "{$keys} = " . $values . " ";
}
$sql = substr($sql, 0, -2) . " WHERE {$this->table_id} = '{$this->id}'";
Please try this:
$key = ':dato';
$arr = $this->v;
if (array_key_exists($key, $this->v) {
unset($arr[$key]);
$this->v = $arr;
}
Try using unset() function.
unset($this->v['dato']);

I am trying to build a search query based on the input from users, but I am having problems with the AND and WHERE keywords. Here is the code:
if (isset($_POST['submitBtn'])) {
$gender = $_POST['gender'];
$level = $_POST['level'];
$status = $_POST['status'];
$query = 'SELECT * FROM candidate ';
$where = array();
$criteria = array('gender' => $gender, 'level' => $level, 'status' => $status);
foreach ($criteria as $key => $value) {
if ($value !== 'all') {
$where[] = $key . ' = ' . $value;
}
}
}
The output looks like this:
Array
(
[0] => gender = masculine
[1] => level = low
[2] => status = future
)
If no option is selected, it defaults to 'all' and it is excluded from the $where[].
I need to achieve this, or anything similar:
Array
(
[0] => WHERE gender = masculine
[1] => AND level = low
[2] => AND status = future
)
The WHERE must be appended only if one or more options have been selected and the AND must be appended only if two or more options have been selected.
In the code I am using I have 9 search inputs. To keep it clear I only displayed three in the snippet. Can you please help me figure this out?
Try this:I think you need the whereClause in string not in array,here you can choose any one from two and remove the other one.
<?php
$where=array();$flag=0;// use flag to identify the where/and
$whereClause="";
$criteria = array('gender' => "masculine", 'level' => "low", 'status' => "future");
foreach ($criteria as $key => $value) {
if ($value !== 'all') {
if($flag == 0){
$where[] = " WHERE " .$key . ' = ' . $value;//if you need array
$whereClause='WHERE '.$key . ' = "' . $value.'"';//if you need string
}else{
$where[] = " AND " .$key . ' = ' . $value;
$whereClause .=' AND '.$key . ' = "' . $value.'"';
}
$flag++;
}
}
echo "<pre>";
print_r($where);
echo "</pre>";
echo $whereClause;
?>
You can do this :
$query = 'SELECT * FROM candidate ';
$where='';
$criteria = array('gender' => $gender, 'level' => $level, 'status' => $status);
foreach ($criteria as $key => $value) {
if ($value !== 'all') {
if($where=='')
$where='WHERE '.$key . ' = ' . $value;
else
$where.=' AND '.$key . ' = ' . $value;
}
}
$query.=$where; //final query
You can use simple switch statement too
<?
if (isset($_POST['submitBtn'])) {
$gender = $_POST['gender'];
$level = $_POST['level'];
$status = $_POST['status'];
$query = 'SELECT * FROM candidate ';
$where = array();
$criteria = array('gender' => $gender, 'level' => $level, 'status' => $status);
foreach ($criteria as $key => $value)
{
if ($value !== 'all')
{
switch ($key)
{
case 1:
{
$query = " WHERE " .$key . ' = ' . $value;
break;
}
case 2:
{
$query = " AND " .$key . ' = ' . $value;
break;
}
case 3:
{
$query = " AND " .$key . ' = ' . $value;
break;
}
}
$where[] = $query;
}
}
}
You need to put one incrementer ($inc) and then put the conditions as:
$inc=1;
foreach ($criteria as $key => $value) {
if ($value !== 'all') {
if($inc==1){
$where[] = 'Where '.$key . ' = ' . $value.'';
}else{
$where[] = 'AND '.$key . ' = ' . $value.'';
}
$inc++;
}
}
In My view there is one more clean way of achiving this:
if (isset($_POST['submitBtn'])) {
$gender = $_POST['gender'];
$level = $_POST['level'];
$status = $_POST['status'];
$query = 'SELECT * FROM candidate ';
$where = array("Where 1=1");
$criteria = array('gender' => $gender, 'level' => $level, 'status' => $status);
foreach ($criteria as $key => $value) {
if ($value !== 'all') {
$where[] = 'AND '.$key . ' = ' . $value.' ';
}
}
}
I need to add data in my database and one way or the other the format must be like,
0 - 0 or 1 - 5
i have tryed =>
mysqli_real_escape_string();
but did not work.
i have also tryed changing the sign to / , * , +, exp.
PHP
$dataBase->_insertDataBase('tableNaam', $input);
function _insertDataBase($tabel,$input){
$velden='';
$waarden='';
$i=0;
foreach($input AS $key=>$value){
$i=$i+1;
if($i !== count($input)){
$a=', ';
}else{
$a='';
}
$velden.=$key.$a;
$waarden.=$value.$a;
unset($a);
}
$sql = "INSERT INTO `$tabel`($velden) VALUES ($waarden)";
$this->_conn()->query($sql);
}
The problem is your SQL statement is giving the equation 5-1 as a value, so the server is doing the math and inserting 4 just like you told it to. You need tell it that it's a literal string by surrounding the values with apostrophe's (i.e. '5-1').
Replace:
foreach ($input AS $key => $value) {
$i = $i + 1;
if ($i !== count($input)) {
$a = ', ';
} else {
$a = '';
}
$velden .= $key . $a;
$waarden .= $value . $a;
unset($a);
}
With:
$velden = array();
$waarden = array();
foreach ($input AS $key => $value) {
$velden[] = $key;
$waarden[] = $value;
}
$velden = implode(',', $velden);
$waarden = "'" . implode("','", $waarden) . "'";
Or possibly even:
$velden = array_keys($input);
$waarden = array_values($input);
$velden = implode(',', $velden);
$waarden = "'" . implode("','", $waarden) . "'";
i want to create HTML element with PHP functions. in this section i have select function to create select tag. for values i want to check if array is simple my function create simple select otherwise create optgroup for options.
my create select method :
$tag->select( 'myselect',
array(
'0'=>'please choose','1'=>'111','2'=>'222','3'=>'333'
) ,
'2',
array(
'class'=>'myClass','style'=>'width:10%;'
)
);
other use:
$tag->select( 'myselect',
array( 'one'=>
array('0'=>'please choose','1'=>'111','2'=>'222','3'=>'333'),
'two'=>
array('0'=>'please choose','1'=>'111','2'=>'222','3'=>'333')
) ,
'2',
array(
'class'=>'myClass','style'=>'width:10%;'
)
) ;
now in below function i want to check if array into array exist function must be create select group;
public function select( $name, $values, $default='0', $attributs=[]){
$options = [];
$selected = '';
echo count($values);
if ( count($values) == 1){
foreach ($values as $value => $title) {
if ( $value === $default ) $selected="selected='selected'";
$options[] = "<option value = '$value' $selected>" . $title . '</option>'.PHP_EOL ;
$selected = '';
}
}
else{
foreach ($values as $key => $value) {
$options[] = "<optgroup label='$key'>";
foreach ($value as $selectValue => $title) {
$options[] = "<option value = '$selectValue'>" . $title . '</option>'.PHP_EOL ;
}
$options[] = "</optgroup>";
}
}
$selectTag = '<select ' . $this->setAttribute($attributs) . '>'.PHP_EOL;
return $selectTag . implode($options, ' ') . '</select>';
}
this function is not correct. how to resolve that? thanks.
Try this (hopefully helps you)
public function select( $name, $values, $default='0', $attributs=[]){
$options = [];
$selected = '';
echo count($values);
foreach ($values as $key => $value) {
if (!is_array($value)) {
if ( $key === $default ) $selected="selected='selected'";
$options[] = "<option value = '$key' $selected>" . $value . '</option>'.PHP_EOL ;
$selected = '';
}
else {
$options[] = "<optgroup label='$key'>";
foreach ($value as $selectValue => $title) {
$options[] = "<option value = '$selectValue'>" . $title . '</option>'.PHP_EOL ;
}
$options[] = "</optgroup>";
}
}
$selectTag = '<select ' . $this->setAttribute($attributs) . '>'.PHP_EOL;
return $selectTag . implode($options, ' ') . '</select>';
}
$resultUpdate = Nemesis::select("*", $table, "id = '{$id}'");
if (!$resultUpdate) {
self::show_error(QUERY_ERROR);
} elseif ($resultUpdate->num_rows > 0) {
$out .= '<div class="form-desc">' . $formDesc . '</div>';
} else {
self::show_error(QUERY_EMPTY);
}
$array = array_values($array);
print_r($array);
$out .= '<form action="' . $_SERVER['PHP_SELF'] . '?id=' . $id . '&table=' . $table . '" method="post" class="form-horizontal" ' . $formAppend . '>';
while ($row = $resultUpdate->fetch_assoc()) {
foreach ($row as $fieldname => $value) {
if (in_array($fieldname, $array)) {
$out .= generateInputField($fieldname, $value);
}
}
foreach ($row as $fieldname => $value) {
if (in_array($fieldname, $array)) {
$out .= generateTextarea($fieldname, $value, $cke);
}
}
foreach ($row as $fieldname => $value) {
if (in_array($fieldname, $array)) {
$out .= generateImgField($fieldname, $value);
}
}
}
$arr = array("last_modified"=>"input", "published"=>"input", "content"=>"textarea");
echo $automate->createArrayForm('projects', 'update', 'Some form desc', '178514825', $arr, true);
Right now all fields are outputting in every foreach when only inputs should output in the generateInputField section for example. I know this is because I need to check if the fieldtype (input, textarea) key matches with one of the values marked as input or textarea for values of the $fieldname. But I am not sure how.
I am pretty sure I have to filter the array so only values with input go into a separate array like arrayInput in which I can use as the second argument in in_array.
If I understand you and your code correctly...
This code
while ($row = $resultUpdate->fetch_assoc()) {
foreach ($row as $fieldname => $value) {
if (in_array($fieldname, $array)) {
will always return true for all your rows thats why you are getting your current output.
Instead you should be doing this:
while ($row = $resultUpdate->fetch_assoc()) {
foreach ($row as $fieldname => $value) {
if ($fieldname == 'input') {
$out .= generateInputField($fieldname, $value);
} elseif($fieldname == 'textarea') {
$out .= generateTextarea($fieldname, $value, $cke);
} elseif ($fieldname == 'img') {
$out .= generateImgField($fieldname, $value);
}
else{ $out = $out;}
}
}

I have a function which performs a foreach loop on an array from a database.
see foreach ($teamarray AS $key => $value){$teamgo .= $value[1]." ".$value[2]."<br/>";
Problem is, sometimes there may be no data set, which throws an error when the loop hits that field.
How can i catch/suppress this error?

$push .= "<div id=unsubmitted><h2>Check which event/teams you want to process and click submit</h2>";

If possible id like it to say "no team selected" and stop.
You can write so:
foreach ((array)$teamarray as $key => $value) {
$teamgo .= $value[1] . " " . $value[2] . "<br/>";
//...
}
foreach expects array. So the really correct way is to ensure that you deal with array before try to iterate, like this:
if (is_array($teamarray) && count($teamarray)) {
foreach ((array)$teamarray as $key => $value) {
$teamgo .= $value[1] . " " . $value[2] . "<br/>";
//...
}
}
You also can check is_iterable since PHP 7.1.
if ($array) {
foreach ($array as $k => $v) {
...
}
} else {
echo 'No team selected';
// exit from loop
}
Your exit from loop will be a "return", or a "break n" (n is the levels to break for) or continue... it depends on your logic.
if ($value !== null && count($value) >= 3) {
$teamgo .= $value[1] . $value[2]
}
<insert puzzled smiley here>
foreach($row AS $key => $value) {
if ($value) {
$row[$key] = stripslashes($value);
}
}
And:
foreach ($teamarray AS $key => $value){
if ($value && sizeof($value) > 2) {
$teamgo .= $value[1] . $value[2]
}
}
Is this it?
Just do a test if $teamarray actually is an array:
if (is_array($teamarray)) {
foreach ($teamarray as $key => $value) {
// …
}
}
Or you could do:
$teamarray = isset($teamarray) ? $teamarray : array();
Just prior to the loop in a nice tidy line, and it would ensure that you have the variable set to an empty array which would cause it to skip the foreach().
