How to concat the foreach loop with string in PHP like this
$traning [] = '<tr>
<td style="width:30%" id="trainingCode_' . $key + 1 . '">
<select class="select2 form-control" data-live-search= "true" name="trainingCode[]">
<option value="0">SELECT CODE</option>'.
foreach ($code=0 as $row) {
//
}
.'</select>
</td>
</tr>';
Split code into parts that are clear to everyone:
$trContent = '<tr>
<td style="width:30%" id="trainingCode_' . $key + 1 . '">
<select class="select2 form-control" data-live-search= "true" name="trainingCode[]">
<option value="0">SELECT CODE</option>';
// iterate over array and append to `$trContent`
foreach ($code as $row) {
$trContent .= '<option></option>';
}
$trContent .= '</select>
</td>
</tr>';
$traning [] = $trContent;
'<option></option>' i have also added my answer with few suggestions.You have few issues in your code:
Issue 1: you can't concat function as like a variable, you just need to break your code and store in a variable then use Concat, otherwise, this will give you parse error.
Issue 2: Dont know why are you using $code=0 as $row in your foreach, this will give you Invalid argument error.
Issue 3: This is just my assumption, according to this id="trainingCode_' . $key + 1 . '" you are using this code inside a loop, if yes then this part name="trainingCode[]" also will create an issue when you fetch record, how would you know the correct relation?
Your Code Example:
<?php
$myString = '<tr>
<td style="width:30%" id="trainingCode_' . $key + 1 . '">
<select class="select2 form-control" data-live-search= "true" name="trainingCode[]">
<option value="0">SELECT CODE</option>';
// use your foreach loop here
foreach ($code as $row) {
$myString .= '<option value="'.$row.'">'.$row.'</option>'; // contact wit $myString
}
$myString .= '</select></td></tr>';
$traning[] = $myString;
?>
value attribute value. Just use ...<option>' . implode('</option><option>', $code) . '</option>...Foreach loop inside string not the best way. But string in string.
$options = "";
foreach ($rows as $code) {
$options .= '<option value="'.$code '">' . $code . '</option>';
}
$traning [] = '<tr>
<td style="width:30%" id="trainingCode_' . $key + 1 . '">
<select class="select2 form-control" data-live-search= "true" name="trainingCode[]">
<option value="0">SELECT CODE</option>'. $options .
'</select>
</td>
</tr>';
value attribute value. Just use ...<option>' . implode('</option><option>', $code) . '</option>...You can do something like:
$options = "";
foreach ($code=0 as $row) {
$options .= "<option value='$code'>Code</option>";
}
$traning [] = '<tr>
<td style="width:30%" id="trainingCode_' . $key + 1 . '">
<select class="select2 form-control" data-live-search= "true" name="trainingCode[]">
<option value="0">SELECT CODE</option>'.
$options
.'</select>
</td>
</tr>';
Code will make it hard for users to know exactly which value they are selecting because all options will have the same visible text.$htmlToConcat = "";
foreach ($code=0 as $row) {
$htmlToConcat .= "";
}
$traning [] = '<tr>
<td style="width:30%" id="trainingCode_' . $key + 1 . '">
<select class="select2 form-control" data-live-search= "true" name="trainingCode[]">
<option value="0">SELECT CODE</option>'.$htmlToConcat.'</select>
</td>
</tr>';
<option> tags. Low-quality answer, rushed answer.
